Description

Technical Field

[0001] The invention relates to the technical field of powder material conveying, in particular to integrated equipment for quantitative conveying of melamine resin powder and automatic recovery of residual material. Background Art

[0002] Melamine resin powder, as an important chemical raw material, is widely used in many fields. For example, in the tableware manufacturing industry, melamine tableware is deeply favored by consumers due to its lightness, aesthetics, low-temperature resistance, and non-fragility. Melamine resin powder is the key raw material for the production of melamine tableware. In the use of melamine resin powder, quantitative delivery and residual material recovery are two important links. At present, many manufacturers still use more traditional methods for quantitative delivery. Some companies rely on manual measurement and delivery with electronic scales. This method not only consumes a lot of manpower, but also has extremely low feeding efficiency. Manual operation is highly subjective, and it is difficult to ensure that the amount of melamine resin powder delivered each time is completely consistent, resulting in inaccurate measurement, which seriously affects the quality stability and production efficiency of subsequent products. In addition, some companies use automated quantitative delivery equipment, but its accuracy has certain problems and cannot meet the production process that requires extremely precise melamine resin powder dosage.

[0003] In terms of 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. The existing waste material recycling mostly relies on manual cleaning, which is cumbersome and inefficient, making it difficult to fully and thoroughly recycle the waste materials.

[0004] The existing Chinese patent with the authorization announcement number CN211440608U discloses a powder quantitative unloading device, which belongs to the field of powder feeding technology and specifically includes: a unloading component, a conveying auger, a quantitative component and a recovery component. The residual material recovery component includes an exhaust fan, a recovery barrel and a negative pressure pipe connecting the exhaust fan and the recovery barrel. The negative pressure pipe is arranged on the unloading pipe and connected thereto; the unloading pipe is provided with a baffle plate that can open and close the unloading pipe and the negative pressure pipe, and the baffle plate is hinged to the pipe wall of the unloading pipe. When weighing, the baffle plate blocks the negative pressure pipe and the residual material recovery component does not work. When weighing is completed, the baffle plate blocks the unloading pipe, and the residual material recovery component starts to suck the residual material in the conveying auger and the unloading pipe into the recovery barrel, thereby realizing the recycling of materials, effectively reducing costs, and reducing material loss and waste.

[0005] However, since the above technical solution does not combine material unloading with residual material recovery, it is necessary to introduce additional negative pressure suction equipment. The process is complicated and occupies a large area, which affects production efficiency. Therefore, a material unloading and conveying equipment that integrates the two steps is needed to optimize the processing steps and improve production efficiency. Summary of the Invention

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" 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 various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0037] Example 1

[0038] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides an integrated device for quantitative conveying of melamine resin powder and automatic recovery of residual materials, realizing the integration of loading and unloading cycles, improving work efficiency and unloading accuracy, and at the same time eliminating unloading gaps through the residual material recovery assembly while recovering residual materials.

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

[0040] The bracket 100 includes a feed tank 101 fixed on the bracket 100;

[0041] The transmission assembly includes a discharge barrel 200 connected to the lower portion of the discharge tank 101, a material transfer column 201 rotatably arranged on the inner wall of the discharge barrel 200, and a pusher head 202 slidably arranged in the material transfer column 201. Two pushers 202 are symmetrically provided, and the outer wall of one end of the pusher head 202 matches the outer wall of the discharge barrel 200 to form a complete cylindrical surface;

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

[0043] The residual material recovery assembly includes a rack 400 provided at one end of the pusher head 202 and a slide rod 401 provided at one end of the rack 400. The slide rod 401 is slidably embedded in another symmetrically arranged pusher head 202. When the slide rod 401 and the pusher head 202 slide relative to each other, vibration is generated. When the pusher head 202 vibrates, the residual material is shaken out and the powder gap is eliminated.

[0044] Among them, four through holes are opened in a circumferential array on the discharge barrel 200, including a discharge through hole 2001, a first discharge port 2002, a second discharge port 2003 and a residual material recovery port 2004, and a slideway 2005 is opened through the material transfer column 201.

[0045] As the material transfer column 201 rotates, the pusher head 202 also moves synchronously, thereby recovering the cavity to accommodate the resin powder or pushing out the powder or residual material. At the same time, because the melamine resin powder particles are small and have a certain specific surface area, they are very susceptible to absorbing moisture from the air when the ambient humidity is high. Once damp, the molecular forces between the resin powder particles increase, and they tend to stick to each other, forming lumps. During transportation, the extrusion of equipment and other conditions can also promote the formation of lumps. The lumped resin powder will adhere to the inner walls of the transportation pipe, hopper, etc., creating gaps, reducing the discharge capacity, affecting product quality, and affecting the smooth discharge of materials, thereby reducing production efficiency.

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

[0047] More preferably, each adjacent through hole is arranged vertically at 90°, the unloading through hole 2001 is connected to the unloading tank 101, and the slide 2005 is a cylindrical channel passing through the center of the material transfer column 201. When the material transfer column 201 rotates in the unloading barrel 200 until the slide 2005 is in an up and down vertical state, the slide 2005 is simultaneously coaxially connected to the unloading through hole 2001 and the residual material recovery port 2004.

[0048] More preferably, a collecting bin is provided under the discharge barrel 200 for recovering residual resin powder. When the slide 2005 is set vertically downward, the residual powder automatically falls into the collecting bin under the action of vibration and gravity. In this embodiment, the material transfer column 201 and the first adjusting rod 300 are both rotated manually, and the two push heads 202 are controlled by the first adjusting rod 300 to slide back and forth along the slide 2005. Every time the material transfer column 201 rotates 90°, the push head 202 completes a one-way stroke along the slide 2005. Every time the material transfer column 201 rotates 180°, the push head 202 completes a 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 push head 202 can slide into the first discharge port 2002 or the second discharge port 2003, and various means can be used to achieve vibration between the slide rod 401 and the push head 202. In this embodiment, impact vibration is used, and in other embodiments, oscillators and other technical means can also be used to achieve it.

[0050] During use, the staff rotates the material transfer column 201 until the slide 2005 moves to the upper and lower vertical state, the two push heads 202 approach each other and retract into the slide 2005, and the slide rod 401 continues to slide inside the rack 400 to the maximum range, and the slide rod 401 hits the other push head 202 to generate vibration. At this time, the resin powder in the slide 2005 area near the discharge through hole 2001 falls from the discharge tank 101 into the cavity formed by the slide 2005 and the push head 202. With the impact vibration, the falling powder also generates oscillation motion synchronously , eliminating the gaps between the individual powders and the gaps caused by the accumulation of agglomerated powders, ensuring the accuracy of the discharge amount, the material transfer column 201 rotates into the discharge barrel 200, and the excess is scraped and left in the discharge tank 101, thereby ensuring that the discharge amount is completely consistent each time, ensuring accurate discharge; at the same time, the slide 2005 is in the cavity at one end away from the discharge tank 101, and due to vibration, the powder remaining adsorbed in the slide 2005 falls and detaches and falls vertically into the collection bin below for recovery, thereby achieving the elimination of discharge gaps and the removal and recovery of residual materials at the same time.

[0051] At the same time, when the unloading is completed and the residual material is cleared, the material 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, and the first adjusting rod 300 is rotated at the same time to make the push head 202 slide outward along the slide 2005, and the powder in the slide 2005 at the second discharge port 2003 is pushed outward to realize unloading; at the same time, if the inner wall of the slide 2005 is attached to the agglomerated resin powder, the agglomerated resin material is pushed out again as the push head 202 at the first discharge port 2002 pushes outward, preventing the attached agglomerated powder from contaminating the next unloading process, and at the same time preventing the agglomerated powder from generating gaps that affect the unloading accuracy.

[0052] Example 2

[0053] Reference Figures 1 to 7 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that when the feeding amount is adjusted, the counterweight is adjusted to ultimately adaptively improve the amplitude and vibration effect.

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

[0055] A sliding bar 4004 is provided on one end surface of the semicircular ring 4003 , and an annular groove 4005 is symmetrically provided on the end surface of the rotating disk 4002 , and the sliding bar 4004 is slidably embedded in the annular groove 4005 .

[0056] Among them, the semicircular ring 4003 is in the shape of a half ring, the sliding bar 4004 is in the shape of an arc, and the annular groove 4005 is an annular groove hole symmetrically distributed up and down. When there is no external force, the semicircular ring 4003 is fixedly embedded in the annular groove 4005 and rotates synchronously therewith. When pushed by an external force, the semicircular ring 4003 overcomes the friction and rotates along the annular groove 4005, thereby adjusting the overlapping area of ​​the two semicircular rings 4003. The more the overlapping area of ​​the two is, the stronger the eccentric force is, and the greater the vibration amplitude of the turntable 4002 when it rotates.

[0057] More preferably, a spiral groove 4006 is formed on the outer wall of the slide rod 401 , a matching hole 4007 is formed in the center of the turntable 4002 , a slide post 4008 is formed on the inner wall of the matching hole 4007 , and the slide post 4008 is slidably fitted in the spiral groove 4006 .

[0058] Among them, the sliding rod 401 slides into the cavity 4001 and slides through the matching hole 4007. The spiral groove 4006 is a curved groove in the shape of a spiral line. The sliding column 4008 is always slidably fitted in the spiral groove 4006. Therefore, when the sliding rod 401 produces relative sliding, the spiral groove 4006 drives the sliding 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 is changed, thereby changing the amplitude of the turntable 4002 during rotation, thereby improving the vibration effect on the resin powder.

[0060] In other embodiments, a tooth groove 4009 may be provided on the outer wall of the semicircular ring 4003, a second adjusting rod 4011 may be provided for rotation on the end face of the turntable 4002, a circular disc 4012 may be provided on the end face of the second adjusting rod 4011, and a tooth column 4013 may be provided in a circular array on the end face of the circular disc 4012, and the tooth column 4013 may be meshed and connected with the tooth groove 4009.

[0061] Preferably, the above-mentioned annular array of tooth grooves 4009 is arranged on the outer wall of the semicircular ring 4003, the circumferential array of tooth columns 4013 is arranged on the disk 4012, and the second adjusting rod 4011 is rotatably arranged in the middle position of the two semicircular rings 4003, so that the tooth columns 4013 on the disk 4012 are engaged with the upper and lower semicircular rings 4003 at the same time. When the second adjusting rod 4011 is rotated, the disk 4012 rotates so that the upper and lower semicircular rings 4003 rotate in opposite directions, thereby realizing the adjustment of the counterweight.

[0062] Among them, the second adjustment rod 4011 can be controlled and driven by an embedded micro motor. When the set feeding amount increases, the second adjustment rod 4011 controls the two semicircular rings 4003 to overlap, thereby increasing the eccentricity and amplitude to ensure the vibration effect.

[0063] In summary, when in use, as the slide rod 401 enters the matching 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 feeding amount is increased, in order to ensure the feeding vibration effect, the amplitude needs to be increased. At this time, the operator only needs to drive the second adjusting rod 4011 to rotate, so that the disc 4012 rotates so that the upper and lower semicircular rings 4003 rotate in opposite directions and tend to overlap, thereby adjusting the counterweight and ultimately improving the amplitude and vibration effect.

[0065] Example 3

[0066] Reference Figure 1-Figure 7 This embodiment is based on the previous embodiment, but the difference is that there is no need to rotate the first adjustment rod 300 again when in use. Instead, the reciprocating rotation of the material transfer column 201 automatically realizes the reciprocating movement of the push head 202 in the slide 2005, thereby realizing the integrated adjustment of the material discharge range and amplitude.

[0067] Specifically, the first adjusting rod 300 rotates and penetrates into the interior of the material moving column 201 and is provided with an adjusting wheel 3001 . The adjusting wheel 3001 is engaged with the two racks 400 at the same time. A buffer spring 3002 is sleeved on the outer wall of the sliding rod 401 .

[0068] Among them, the buffer spring 3002 is used to provide buffering, and its two ends are respectively arranged 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 axial position of the discharge barrel 200.

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

[0070] An eccentric column 3006 is provided on the outer wall of the sliding sleeve 3005 , and an eccentric shaft 3007 is provided to rotate through the discharge barrel 200 . An eccentric disk 3008 is provided at one end of the eccentric shaft 3007 located inside the discharge barrel 200 , and the eccentric column 3006 slides through the eccentric disk 3008 .

[0071] Among them, the eccentric column 3006 is eccentrically arranged on the eccentric disk 3008, and the axis of the eccentric column 3006 always crosses the first adjusting rod 300, so that as the eccentric disk 3008 rotates, the eccentric column 3006 is driven to rotate periodically, and at the same time drives the sliding sleeve 3005 to slide along the auxiliary rod 3004, and finally drives the first adjusting rod 300 to realize angular rotation through the swing of the auxiliary rod 3004, and drives the two racks 400 to move in opposite directions through the adjusting wheel 3001, thereby adjusting the initial positions of the two racks 400, and finally realizing the adjustment of the feeding amount of melamine resin powder.

[0072] Preferably, the eccentric shaft 3007 is also started by a micromotor, and the set feeding amount is adjusted by rotating the micromotor, and the micromotor and the micromotor of the second adjusting rod 4011 rotate at the same amplitude, thereby achieving the technical effect of automatically adjusting the corresponding amplitude when the set feeding amount is adjusted, and achieving the beneficial effect of adaptively adjusting the amplitude according to the feeding amount.

[0073] Among them, such as Figure 3 As shown, since the adjusting wheel 3001 is engaged with the two racks 400 at the same time, when the material transfer column 201 rotates clockwise, it is equivalent to the adjusting wheel 3001 rotating counterclockwise, so that the two racks 400 are brought closer to each other. Similarly, when the material transfer column 201 rotates counterclockwise, the two racks 400 drive the push head 202 to slide away. In other embodiments, a redundant design is adopted for the push head 202. When unloading, the push head 202 extends longer than a part of the outside of the material transfer column 201, and the size of the left and right unloading holes is increased, so as to ensure that the rotation of the material transfer column 201 is not affected when the material is completely unloaded, so that the resin powder can still be completely unloaded.

[0074] In summary, when the unloading device is in use, the eccentric column 3006 is fixed after adjustment. It is only necessary to rotate the material transfer column 201 in the forward direction first, so that the two racks 400 begin to periodically reciprocate around the adjustment wheel 3001 located at the center position, so that the two push heads 202 move closer to or farther away from each other, and finally realize the reciprocating cycle of unloading and unloading.

[0075] When it is necessary to adjust the set feeding amount, it is only necessary to start the micro motor, and 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, and at the same time drives the auxiliary rod 3004 to swing through the sliding sleeve 3005, and finally realizes the rotation adjustment of the first adjusting rod 300, and the adjusting wheel 3001 drives the two racks 400 to move in opposite directions, thereby adjusting the initial positions of the two racks 400. At this time, the initial positions of the two push heads 202 are closer, which increases the single feeding amount, and finally realizes the adjustment of the melamine resin powder feeding amount, and simultaneously realizes the technical effect of adaptive adjustment of the amplitude according to the feeding amount.
