Description

Technical Field

[0001] This invention relates to the field of powder conveying technology, and in particular to an integrated device for quantitative conveying and automatic recycling of melamine resin powder. Background Technology

[0002] Melamine resin powder, as an important chemical raw material, has wide applications in many fields. For example, in the tableware manufacturing industry, melamine tableware is favored by consumers for its lightweight, beautiful appearance, low-temperature resistance, and durability. Melamine resin powder is a key raw material in the production of melamine tableware. In the process of using melamine resin powder, quantitative conveying and residual material recovery are two important steps. Currently, many manufacturers still use relatively traditional methods for quantitative conveying. Some companies rely on manual labor combined with electronic scales for metering and conveying. This method not only consumes a lot of manpower but also has extremely low material supply efficiency. Manual operation is highly subjective, making it difficult to ensure that the amount of melamine resin powder conveyed each time is completely consistent, leading to inaccurate measurement and seriously affecting the quality stability and production efficiency of subsequent products. Furthermore, the automated quantitative conveying equipment used by some companies also has certain accuracy problems and cannot meet the extremely precise requirements of production processes that demand precise melamine resin powder dosage.

[0003] Regarding waste material recycling, if the melamine resin powder left over from the production process is not effectively recycled, it will not only cause a huge waste of resources and increase production costs, but may also cause certain pollution to the environment. Most existing waste material recycling relies on manual cleaning, which is cumbersome and inefficient, and it is difficult to fully and thoroughly recycle waste materials.

[0004] Chinese Patent CN211440608U discloses a powder quantitative feeding device, belonging to the field of powder feeding technology. Specifically, it includes a feeding component, a conveying auger, a quantitative component, and a recovery component. The residual material recovery component includes a blower, a recovery hopper, and a negative pressure pipe connecting the blower and the recovery hopper. The negative pressure pipe is located on and connected to the feeding pipe. A baffle plate is provided on the feeding pipe, which can open and close the feeding pipe and the negative pressure pipe. The baffle plate is hinged to the wall of the feeding pipe. In this technical solution, during weighing, the baffle plate blocks the negative pressure pipe, and the residual material recovery component does not operate. At the end of weighing, the baffle plate blocks the feeding pipe, and the residual material recovery component starts, sucking the remaining material in the conveying auger and the feeding pipe into the recovery hopper, realizing material recycling, effectively reducing costs, and minimizing material loss and waste.

[0005] However, since the above technical solutions do not combine material feeding and waste material recycling, additional negative pressure suction equipment is required, which makes the process complex and occupies a large area, affecting production efficiency. Therefore, a material feeding and conveying equipment that integrates the two steps is needed to optimize the processing steps and improve production efficiency. Summary of the Invention

[0010] The stroke adjustment assembly includes a first adjustment rod located between two push heads, which simultaneously controls the two push heads to move synchronously or remain stationary.

[0011] The waste material recovery assembly includes a rack at one end of the pusher and a slide bar at one end of the rack. The slide bar slides into another pusher that is symmetrically arranged.

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an integrated device for quantitative conveying of melamine resin powder and automatic recycling of residual material, realizing integrated feeding and unloading cycles, improving work efficiency and feeding accuracy, and simultaneously eliminating feeding gaps and recycling residual material through the residual material recycling assembly.

[0039] Specifically, the integrated equipment for quantitative conveying and automatic recycling of melamine resin powder includes:

[0040] The support 100 includes a feeding tank 101 fixedly mounted on the support 100;

[0041] The transmission assembly includes a feeding cylinder 200 connected to the bottom of the feeding tank 101, a transfer column 201 rotatably disposed on the inner wall of the feeding cylinder 200, and a pusher 202 slidably disposed in the transfer column 201. Two pushers 202 are symmetrically arranged, and the outer wall of one end of the pusher 202 matches the outer wall of the feeding cylinder 200 to form a complete cylindrical surface.

[0042] The stroke adjustment assembly includes a first adjustment rod 300 located between two push heads 202, which simultaneously controls the two push heads 202 to move synchronously or remain stationary.

[0043] The waste material recovery assembly includes a rack 400 at one end of the pusher 202 and a slide bar 401 at one end of the rack 402. The slide bar 401 slides into another pusher 202 that is symmetrically arranged. When the slide bar 401 slides relative to the pusher 202, it vibrates. When the pusher 202 vibrates, it shakes out the waste material and eliminates the gaps in the powder.

[0044] The feeding cylinder 200 has four through holes arranged in a circular array, including a feeding through hole 2001, a first discharge port 2002, a second discharge port 2003, and a residual material recovery port 2004. A slide 2005 is provided through the material transfer column 201.

[0045] As the transfer column 201 rotates, the pusher 202 moves synchronously, thereby creating a cavity to hold the resin powder or pushing it out to discharge the powder or excess material. Simultaneously, because the melamine resin powder particles are small and have a certain specific surface area, they easily absorb moisture from the air when the ambient humidity is high. Once damp, the molecular forces between the resin powder particles increase, making them prone to sticking together and forming clumps. During transportation, pressure from the equipment can also promote clump formation. Clumped resin powder adheres to the inner walls of transport pipes and hoppers, creating voids, reducing the feed rate, affecting product quality, and hindering smooth feeding, thus reducing production efficiency.

[0046] More preferably, each through hole has the same inner diameter as the slide 2005 and is equal to the outer diameter of the pusher 202. The pusher 202 is cylindrical, with a circular surface on one side and a vertical surface on the other side. The spherical surface matches the end of the slide 2005 to form a complete circular outer wall.

[0047] More preferably, each adjacent through hole is set at a 90° angle vertically. The discharge through hole 2001 is connected to the discharge tank 101. The slide 2005 is a cylindrical channel passing through the center of the transfer column 201. When the transfer column 201 rotates in the discharge cylinder 200 until the slide 2005 is in a vertical position, the slide 2005 is simultaneously coaxially connected to the discharge through hole 2001 and the residual material recovery port 2004.

[0048] More preferably, a collection bin is provided below the feeding cylinder 200 for recovering residual resin powder. When the slide 2005 is set vertically downward, the residual powder will automatically fall into the collection bin under the action of vibration and gravity. In this embodiment, the transfer column 201 and the first adjusting rod 300 are both manually rotated. The first adjusting rod 300 controls the two push heads 202 to slide back and forth along the slide 2005 in a cyclic manner. For every 90° rotation of the transfer column 201, the push head 202 completes one unidirectional stroke along the slide 2005. For every 180° rotation of the transfer column 201, the push head 202 completes one cycle and resets.

[0049] Preferably, when the slide 2005 is coaxially arranged with the first discharge port 2002 or the second discharge port 2003, the pusher 202 can slide into the first discharge port 2002 or the second discharge port 2003. Vibration can be achieved between the slide rod 401 and the pusher 202 by various means. In this embodiment, impact vibration is used. In other embodiments, oscillators and other technical means can also be used respectively.

[0050] During use, the operator rotates the transfer column 201 until the slide 2005 moves to a vertical position. At this point, the two pushers 202 approach each other and retract into the slide 2005. When the slide rod 401 continues to slide within the rack 400 to its maximum range, it impacts another pusher 202, generating vibration. At this time, resin powder near the discharge hole 2001 falls from the discharge tank 101 into the cavity formed by the slide 2005 and the pusher 202. With the impact and vibration, the falling powder also oscillates synchronously. This process eliminates gaps between powder materials and voids caused by the accumulation of clumps, ensuring accurate material feeding. The transfer column 201 rotates into the feeding cylinder 200, and excess material is scraped away and left in the feeding tank 101, thus ensuring that the feeding amount is completely consistent each time and ensuring accurate feeding. At the same time, due to vibration, the residual powder adsorbed in the slide 2005 at the cavity away from the feeding tank 101 falls off and falls vertically into the collection bin below for recycling, thereby simultaneously eliminating feeding gaps and cleaning and recycling residual material.

[0051] Meanwhile, after the unloading is completed and the residual material is cleared, the transfer column 201 continues to rotate clockwise until the slide 2005 moves to a horizontal state. At this time, the two ends of the slide 2005 are aligned with the first discharge port 2002 and the second discharge port 2003 respectively. At the same time, the first adjusting rod 300 is rotated to make the push head 202 slide outward along the slide 2005, pushing the powder in the slide 2005 at the second discharge port 2003 outward to achieve unloading. At the same time, if the inner wall of the slide 2005 is covered with clumps of resin powder, the clumps of resin powder will be pushed outward again as the push head 202 at the first discharge port 2002 pushes it outward, preventing the attached clumps of powder from contaminating the next unloading process, and preventing the clumps of powder from creating gaps that affect the unloading accuracy.

[0052] Example 2

[0053] Reference Figures 1 to 7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that when adjusting the material feed, the amplitude and vibration effect are ultimately adaptively improved by adjusting the counterweight.

[0054] Specifically, the pusher head 202 has a cavity 4001 inside, and a turntable 4002 is rotatably mounted inside the cavity 4001. The slide rod 401 slides through the turntable 4002. Semicircular rings 4003 are provided on both sides of the turntable 4002. The more overlapping areas of the two semicircular rings 4003, the greater the eccentric force when the turntable 4002 rotates.

[0055] Among them, a sliding strip 4004 is provided on one end face of the semi-circular ring 4003, and an annular groove 4005 is symmetrically provided on the end face of the turntable 4002. The sliding strip 4004 is slidably fitted into the annular groove 4005.

[0056] The semicircular ring 4003 is half a circular ring, the sliding bar 4004 is an arc shape, and the annular groove 4005 is a symmetrically distributed annular slot. When no external force is applied, the semicircular ring 4003 is fixedly fitted into the annular groove 4005 and rotates synchronously with it. When pushed by an external force, the semicircular ring 4003 overcomes friction and rotates along the annular groove 4005, thereby adjusting the overlapping area of ​​the two semicircular rings 4003. The greater the overlap area, the stronger the eccentric force, and the greater the vibration amplitude when the turntable 4002 rotates.

[0057] More preferably, the outer wall of the slide bar 401 is provided with a spiral groove 4006, the center of the turntable 4002 is provided with a mating hole 4007, the inner wall of the mating hole 4007 is provided with a sliding column 4008, and the sliding column 4008 is slidably mated in the spiral groove 4006.

[0058] The slide rod 401 slides into the cavity 4001 and slides through the mating hole 4007. The spiral groove 4006 is a spiral-shaped curved groove. The slide column 4008 is always slidably fitted in the spiral groove 4006. So when the slide rod 401 slides relative to the slide rod, the spiral groove 4006 drives the slide column 4008 and the turntable 4002 to rotate.

[0059] In this embodiment, the two semicircular rings 4003 are manually adjusted by the operator. By adjusting the overlapping area of ​​the two semicircular rings 4003, the counterweight of the turntable 4002 changes, thereby changing the amplitude of the rotation of the turntable 4002, resulting in a better vibration effect on the resin powder.

[0060] In other embodiments, the outer wall of the semi-circular ring 4003 may be further provided with a toothed groove 4009, the end face of the turntable 4002 is provided with a second adjusting rod 4011, the end face of the second adjusting rod 4011 is provided with a disc 4012, and the end face of the disc 4012 is provided with a circumferential array of toothed columns 4013, which are meshed with the toothed groove 4009.

[0061] Preferably, the aforementioned toothed grooves 4009 are arranged in annular array on the outer wall of the semicircular ring 4003, and the toothed column 4013 is arranged in circumferential array on the disk 4012. The second adjusting rod 4011 is rotatably positioned in the middle of the two semicircular rings 4003, so that the toothed column 4013 on the disk 4012 simultaneously meshes with the upper and lower semicircular rings 4003. When the second adjusting rod 4011 is rotated, the disk 4012 rotates, causing the upper and lower semicircular rings 4003 to rotate in opposite directions, thereby adjusting the counterweight.

[0062] The second adjusting rod 4011 can be controlled and driven by an embedded micro motor. When the set feeding amount increases, the second adjusting rod 4011 controls the two semicircular rings 4003 to tend to overlap, thereby improving the eccentricity and amplitude and ensuring the vibration effect.

[0063] In summary, during use, as the slide rod 401 enters the mating hole 4007 and continues to slide in, the slide column 4008 drives the turntable 4002 to rotate along the spiral groove 4006, thereby causing the two semicircular rings 4003 on the turntable 4002 to rotate synchronously.

[0064] When the set feed amount increases, the amplitude needs to be increased to ensure the feeding vibration effect. At this time, the operator only needs to drive the second adjusting rod 4011 to rotate, so that the disc 4012 rotates and the upper and lower semicircular rings 4003 rotate in opposite directions to tend to overlap, thereby adjusting the counterweight and ultimately improving the amplitude and vibration effect.

[0065] Example 3

[0066] Reference Figures 1-7 This embodiment is based on the previous embodiment, but the difference is that it does not require rotating the first adjusting rod 300 again during use. Instead, the pusher 202 is automatically moved back and forth in the slide 2005 by the reciprocating rotation of the material transfer column 201, so as to realize the integrated adjustment of the feeding range and amplitude.

[0067] Specifically, the first adjusting rod 300 rotates through the material transfer column 201 and is equipped with an adjusting wheel 3001. The adjusting wheel 3001 is simultaneously engaged with two racks 400, and a buffer spring 3002 is sleeved on the outer wall of the slide rod 401.

[0068] Among them, the buffer spring 3002 is used to provide buffering, and its two ends are respectively located on the side of the rack 400 and connected to the right angle surface of the push head 202. The adjusting wheel 3001 and the first adjusting rod 300 are located at the axis position of the feed cylinder 200.

[0069] More preferably, a fixed support plate 3003 is vertically provided at one end of the first adjusting rod 300, an auxiliary rod 3004 is provided at one end of the fixed support plate 3003, and a sliding sleeve 3005 is slidably sleeved on the outer wall of the auxiliary rod 3004;

[0070] The outer wall of the sliding sleeve 3005 is provided with an eccentric column 3006, and the feed cylinder 200 is rotatably provided with an eccentric shaft 3007. One end of the eccentric shaft 3007 located inside the feed cylinder 200 is provided with an eccentric disc 3008, and the eccentric column 3006 slides through the eccentric disc 3008.

[0071] The eccentric column 3006 is eccentrically set on the eccentric disk 3008. The axis of the eccentric column 3006 always intersects with the first adjusting rod 300. As the eccentric disk 3008 rotates, the eccentric column 3006 rotates periodically, which in turn drives the sliding sleeve 3005 to slide along the auxiliary rod 3004. Finally, the auxiliary rod 3004 swings to drive the first adjusting rod 300 to rotate at an angle. The adjusting wheel 3001 drives the two racks 400 to move in opposite directions, thereby adjusting the initial position of the two racks 400 and ultimately adjusting the amount of melamine resin powder fed.

[0072] Preferably, the eccentric shaft 3007 also has a micro motor that starts, and the set feeding amount is adjusted by rotating the micro motor. The micro motor rotates at the same amplitude as the micro motor of the second adjusting rod 4011, thereby achieving the technical effect of automatically adjusting the corresponding amplitude when the set feeding amount is adjusted, and realizing the beneficial effect of adaptive adjustment of amplitude according to the feeding amount.

[0073] Among them, such as Figure 3 As shown, since the adjusting wheel 3001 meshes with both racks 400 simultaneously, when the transfer column 201 rotates clockwise, it is equivalent to the adjusting wheel 3001 rotating counterclockwise, causing the two racks 400 to move closer to each other. Similarly, when the transfer column 201 rotates counterclockwise, the two racks 400 drive the push head 202 to slide away. In other embodiments, the push head 202 is designed with redundancy. When discharging, the push head 202 extends beyond the outside of the transfer column 201, and the opening size of the left and right discharge holes is increased, so as to ensure that the rotation of the transfer column 201 is not affected when the material is fully discharged, so that the resin powder is still completely unloaded.

[0074] In summary, when the feeding device is in use, the eccentric column 3006 is fixed after adjustment. Only the material transfer column 201 needs to be rotated in the forward direction first, so that the two racks 400 start to rotate periodically around the adjusting wheel 3001 located at the center, so that the two pushers 202 move closer or further away from each other, and finally realize the reciprocating cycle of feeding and unloading.

[0075] When the set feeding amount needs to be adjusted, simply start the micro motor. The rotation of the eccentric shaft 3007 drives the eccentric disk 3008 to rotate, and the eccentric column 3006 is driven to move synchronously, sliding up and down in the vertical direction. At the same time, the sliding sleeve 3005 drives the auxiliary rod 3004 to swing, ultimately realizing the rotation adjustment of the first adjusting rod 300. The adjusting wheel 3001 drives the two racks 400 to move in opposite directions, thereby adjusting the initial position of the two racks 400. At this time, the initial positions of the two pushers 202 are closer, increasing the feeding amount per batch. Ultimately, the feeding amount of melamine resin powder is adjusted, and the amplitude is simultaneously adjusted adaptively according to the feeding amount.
