During the processing and molding process, an automatic feeding device is usually used to inject the granular polymer materials into the mold to improve the processing and molding efficiency of the polymer granular materials. The existing polymer materials use a variety of methods to achieve automatic feeding, such as a fully automatic suction device for polymer material display processing with a publication number of CN211393104U, which includes a box body, one side of the box body is connected to a feed pipe, and the other side of the box body is provided with a negative pressure pump connected to the inner cavity, two groups of inclined sieve plates are symmetrically arranged in the inner cavity of the box body, a connecting rod is movably inserted at the top of the box body, and a pressure plate that contacts and cooperates with the sieve plate is fixedly connected to the bottom of the connecting rod, an operating box is fixedly arranged at the upper end of the box body, grinding boxes are arranged at the lower end of the sieve plate on the two walls of the inner cavity of the box body, and connecting pipes connecting the bottom of the sieve plate and the grinding box are symmetrically arranged on the outer side of the box. When feeding polymer granular materials, the existing feeding device usually only uses a filter screen to screen the polymer particles.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: Reference Figure 1-Figure 3An automatic feeding device for polymer material molding includes a storage barrel 2 arranged on a support frame 1 for feeding and storing polymer particle materials. The whole process of polymer particle sorting, storage and feeding is realized in the storage barrel 2 without generating dust leakage.

[0025] The automatic feeding device also includes: The sorting unit is arranged in the storage barrel 2, and is used to realize the feeding and color sorting of polymer particles, and to clean up the debris during the color sorting process. During the feeding process of polymer particles, polymer particles of different colors are stored independently, and dust in the polymer particles and broken polymer particles generated during the color sorting are sucked out; The feeding unit is arranged in the storage barrel 2, and is used to realize the storage and quantitative feeding of polymer particles, and can realize the effective screening of good and defective polymer particles, while avoiding blockage, and realizing the accurate feeding of polymer particles; A control console is provided on the support frame 1, and the control console cooperates with the sorting unit and the feeding unit to realize the programmed operation of the sorting unit and the feeding unit, and realize the automatic feeding of polymer particles with a higher degree of automation.

[0026] Example 2: Reference Figure 3-Figure 9 The technical solution of this embodiment is different from that of the first embodiment in that the sorting unit includes a feeding component, a color sorting component and a slag removal component, wherein the feeding component is used to transport the polymer particles into the color sorting component for sorting and unloading, and the slag is removed by the slag removal component during the color sorting process; A partition plate 6 for partitioning is provided inside the storage barrel 2, and the partition plate 6 plays a role in partitioning the inside of the storage barrel 2, realizing partition-type feeding, and preventing the diffuse dust generated when the polymer particles are fed on the left side from affecting the space on the right side of the storage barrel 2; The feeding assembly includes a feeding hopper 3 fixedly mounted on a storage barrel 2 for feeding polymer particles, a conduction box 10 is fixedly arranged in the storage barrel 2, and the conduction box 10 is connected to the feeding hopper 3, and a distribution box 11 is fixedly arranged in the storage barrel 2, and the distribution box 11 is connected to the lower part of the distribution box 10; The polymer particles are poured into the conduction box 10 through the feed hopper 3, and are conducted to the separation box 11 through the conduction box 10, and are led out after being sorted by the color sorting component in the separation box 11, thereby realizing the automatic conduction discharge of the polymer particles.

[0027] In a further embodiment, the color sorting assembly includes two symmetrical color sensors 20 fixedly disposed in the conductive box 10, the two color sensors 20 are used to identify the color of the polymer particles, a fixed plate 19 is fixedly installed in the material distribution box 11, and a controller matching the color sensors 20 is disposed in the fixed plate 19; Attached to the instruction manual Figure 7 As shown, when the polymer particles fall through the conductive box 10, they will pass between the two color sensors 20 inside the conductive box 10 and then fall. At this time, the color sensor 20 will identify the colors of the multiple polymer particles, that is, accurately identify the color of each polymer particle, and divide it into dark colors and light colors, and at the same time transmit the identified color results to the controller for recording.

[0028] A plurality of micro motors are arranged in the fixed plate 19, and a swing wheel 26 is fixedly mounted on the driving end of each micro motor, and a striking screening plate 25 for picking and beating polymer particles is fixedly mounted on the lower part of each swing wheel 26; The controller will record the color of each polymer particle and the vertical position of the falling polymer particle. When the polymer particle passes through the conductive box 10 and is at the horizontal position of the fixed plate 19, the micro motor at the corresponding position in the fixed plate 19 will be started, thereby driving the swing wheel 26 to rotate. When the swing wheel 26 rotates, it will drive the corresponding striking screening plate 25 at its lower part to rotate and hit the polymer particles of different colors falling vertically, thereby knocking the polymer particles of different colors away, completing the color sorting of the polymer particles. The color sensor 20 is a device that can detect the color of the surface of an object. It is a device commonly used in the prior art to detect and identify the color of materials. It is used in this application document to detect and identify the color of polymer particles. This part is prior art and will not be elaborated on here.

[0029] For example: if the overall number of polymer particles to be loaded is mostly light-colored and less dark-colored, at this time, when the polymer particles are fed, the large number of light-colored polymer particles fall vertically and are collected, while the small number of dark-colored polymer particles are separated. At this time, the color sensor 20 will identify and mark the position of the small number of dark-colored polymer particles, and while falling, through the control of the controller and multiple micromotors, drive the multiple striking screening plates 25 to rotate and accurately knock out the small number of dark-colored polymer particles, so as to separate them from the light-colored polymer particles, thereby completing the color sorting of the polymer particles.

[0030] In a further embodiment, a servo motor 4 is disposed outside the support frame 1, and a driving roller 15 is rotatably installed between the driving end of the servo motor 4 and the storage barrel 2, and the servo motor 4 starts to drive the driving roller 15 to rotate; The slag removal assembly includes an air-inducing round box 16 fixedly installed in the storage barrel 2, and the air-inducing round box 16 is rotatably connected to the driving roller 15, and the driving roller 15 is provided with a wind impeller 23 through a one-way bearing 2 37, and the one-way bearing 2 37 cooperates with the positive rotation of the driving roller 15, and the wind impeller 23 is located in the air-inducing round box 16, and an exhaust pipe for exhaust is provided between the air-inducing round box 16 and the storage barrel 2, and a blocking plate 22 is fixedly installed in the air-inducing round box 16, and a plurality of slag-blocking holes 24 are opened on the blocking plate 22, and two impurity suction boxes 21 for absorbing broken slag are fixedly connected between the air-inducing round box 16 and the distribution box 11; When the servo motor 4 drives the driving roller 15 to rotate in the forward direction, the one-way bearing 2 37 is driven to rotate, thereby driving the impeller 23 to rotate. When the impeller 23 rotates, air is sucked through the slag blocking hole 24 on the blocking plate 22, and then air is sucked into the distribution box 11 through the two suction boxes 21; When the polymer particles are fed and fall, a certain amount of dust will be generated. At the same time, when the impact screening plate 25 hits the polymer particles, some polymer particles that are not firmly bonded will be broken, thereby producing broken polymer particle debris. At this time, the suction box 21 can simultaneously absorb the polymer particle debris and dust in the distribution box 11 while absorbing air, so as to avoid the dust and debris from mixing in the intact polymer particles, which will affect the subsequent molding quality of the polymer particles.

[0031] The material distribution box 11 is provided with a plurality of air supply holes 17 for supplying air, and the air supply holes 17 are used to supply air to the inside of the material distribution box 11 to avoid insufficient air pressure in the material distribution box 11 when inhaling air; A slag removal square pipe 14 for slag discharge is provided between the draft box 16 and the storage barrel 2. The dust and debris sucked away by the impurity suction box 21 will be blocked by the blocking plate 22 and fall to the bottom of the draft box 16. After the polymer particles are fed, the waste slag sucked away can be cleaned up by the slag removal square pipe 14.

[0032] Example 3: Reference Figure 3-4 as well as Figure 10-Figure 14 The technical solution of this embodiment is different from that of the second embodiment in that: the loading unit includes a storage component, a vibration component and a metering and discharging component. The storage component is used to store polymer particles. The vibration component cooperates with the metering and discharging component to realize quantitative discharging of polymer particles and avoid accumulation and blockage during discharging. The storage assembly includes two discharging square tubes 12 fixedly connected to the lower part of the material distribution box 11. A material distribution triangle plate 18 is fixedly installed in the material distribution box 11. The material distribution triangle plate 18 plays a barrier role to prevent polymer particles of different colors from mixing again after separation. The two discharging square tubes 12 are respectively located on both sides of the material dividing triangle plate 18. Two material storage boxes 7 are arranged in the material storage barrel 2, and the two material storage boxes 7 are provided with receiving openings 27 that match the corresponding discharging square tubes 12. When the polymer particles are fed and fall, a larger number of light-colored polymer particles will fall directly and be discharged through the left discharge square tube 12, while a smaller number of dark-colored polymer particles will fall to the right side of the material distribution box 11 after being hit, and then be discharged through the right discharge square tube 12, so that the light-colored polymer particles and the dark-colored polymer particles can be discharged and collected separately; The polymer particles discharged through the discharge square tube 12 will fall vertically and fall into the storage box 7 through the receiving opening 27 on the storage box 7, thereby completing the collection of the polymer particles.

[0033] In a further embodiment, the vibration component includes a screening filter 28 slidably installed in the storage box 7 for screening polymer particles, and the screening filter 28 is inclined. The lower part of the storage box 7 is fixedly connected to a discharge square pipe 13 for discharging defective products. The screening filter 28 is used to screen the polymer particles, so that the smaller defective products in the polymer particles that do not meet the requirements and the remaining dust and debris mixed in the polymer particles can fall through the screening filter 28 and fall to the bottom of the storage box 7 for collection, and finally are discharged through the discharge square pipe 13 for reprocessing, while the qualified polymer particles that meet the requirements will remain on the upper part of the screening filter 28, thereby completing the screening of good and inferior polymer particles.

[0034] An incomplete gear 32 is provided on the driving roller 15 through a one-way bearing 31, a support plate is fixedly installed in the storage barrel 2, and a vibrating tooth plate 33 matching the incomplete gear 32 is provided on the support plate through two vibrating springs 34, a linkage mechanism is installed between the vibrating tooth plate 33 and the screening filter 28, and a discharge square pipe 13 for discharging defective materials is fixedly connected to the lower part of the storage box 7; When the servo motor 4 starts to drive the driving roller 15 to rotate in the opposite direction, the incomplete gear 32 will be driven to rotate under the cooperation of the one-way bearing 31. Since the incomplete gear 32 cooperates with the vibrating tooth plate 33, when the incomplete gear 32 rotates to mesh with the vibrating tooth plate 33, the vibrating tooth plate 33 will be driven to move downward and squeeze the lower vibration spring 34. When the incomplete gear 32 rotates to no longer mesh with the vibrating tooth plate 33, the vibrating tooth plate 33 will rise and reset under the rebound action of the vibration spring 34. When the incomplete gear 32 continues to mesh with the vibrating tooth plate 33, the vibrating tooth plate 33 continues to move downward. When the incomplete gear 32 is repeated, the reciprocating and uninterrupted vertical lifting vibration of the vibrating tooth plate 33 can be achieved.

[0035] The linkage mechanism includes a linkage folding rod 29 fixedly mounted on a vibrating tooth plate 33, a lifting vibration rod 30 fixedly mounted on the screening filter 28, an electromagnetic clamp 36 fixedly mounted on the lifting vibration rod 30, and an electromagnetic clamp 35 matched with the electromagnetic clamp 36 fixedly mounted on the linkage folding rod 29; When the vibrating tooth plate 33 is lifted or lowered, the linkage folding rod 29 thereon will be driven to lift or lower. When the polymer particles in the storage box 7 on the left need to be vibrated for discharge, the electromagnetic card block 36 and the electromagnetic card component 35 on the left will be started and energized, that is, the electromagnetic card block 36 on the left will be locked and adsorbed in the electromagnetic card component 35 on the left. At this time, when the linkage folding rod 29 is lifted or vibrated, the electromagnetic card component 35 will be driven to lift or vibrate, thereby driving the electromagnetic card block 36 to vibrate, and then driving the screening filter 28 to lift or vibrate through the lifting vibration rod 30.

[0036] In a further embodiment, when the screening filter 28 is lifted and vibrated, since the screening filter 28 is tilted, the polymer particles thereon will gradually vibrate and slide from the left side to the right side when the screening filter 28 vibrates, thereby realizing automatic sliding discharge of the polymer particles. While vibrating and discharging, the vibration effect of the polymer particles can also be increased, which can avoid the accumulation and blockage of the polymer particles and accelerate the screening effect of defective products and debris dust inside the polymer particles.

[0037] Each material storage box 7 is provided with a metering discharging assembly, which includes a material guide pipe 8 fixedly connected to the material storage box 7 for conducting polymer particles, and the material guide pipe 8 is located on the upper part of the screening filter 28, and the lower part of the material guide pipe 8 is fixedly connected to a weighing barrel 9 for temporarily storing and measuring the weight of polymer particles, and a feeding pipe 5 is fixedly connected between the weighing barrel 9 and the material storage barrel 2; When the screening filter 28 vibrates to screen and discharge materials, the high-quality polymer particles on it will fall into the guide tube 8 when sliding to the rightmost side, and then fall into the weighing bucket 9 through the guide tube 8. At this time, the weighing bucket 9 will accurately weigh the weight of the polymer particles. When the weighed weight meets the discharge requirements, the guide tube 8 is closed to stop the discharge, and then the feeding tube 5 is opened to guide the quantitative polymer particles in the weighing bucket 9, thereby realizing the accurate measurement and discharge of the polymer particles.

[0038] The specific feeding principle of the feeding device is as follows: the polymer particles are poured into the conductive box 10 through the feed hopper 3. When the polymer particles fall through the conductive box 10, they pass between the two color sensors 20 inside the conductive box 10 and then fall. At this time, the color sensor 20 will identify the colors of the multiple polymer particles, that is, accurately identify the color of each polymer particle. The controller will record the color of each polymer particle and the vertical position of its fall. When the polymer particles pass through the conduction box 10 and are in the horizontal position of the fixed plate 19, the micro motor at the corresponding position in the fixed plate 19 will be started, thereby driving the swing wheel 26 to rotate. When the swing wheel 26 rotates, it will drive the corresponding striking screening plate 25 at its lower part to rotate and hit the vertically falling polymer particles of different colors, thereby knocking the polymer particles of different colors away and completing the color sorting of the polymer particles.

[0039] While color sorting, the servo motor 4 is started to drive the driving roller 15 to rotate in the forward direction, and then the impeller 23 is driven to rotate through the one-way bearing 2 37. When the impeller 23 rotates, air is sucked through the slag blocking hole 24 on the blocking plate 22, and then air is sucked into the material separation box 11 through the two impurity suction boxes 21; When the polymer particles are fed and fall, a certain amount of dust will be generated. At the same time, when the impact screening plate 25 hits the polymer particles, some polymer particles that are not firmly bonded will be broken, thereby producing broken polymer particle debris. At this time, the suction box 21 can simultaneously absorb the polymer particle debris and dust in the distribution box 11 while absorbing air, so as to avoid the dust and debris from mixing in the intact polymer particles, which will affect the subsequent molding quality of the polymer particles.

[0040] When the feed material falls, the polymer particles are discharged through the discharge square tube 12 and fall vertically, and fall into the storage box 7 through the receiving opening 27 on the storage box 7, completing the collection of the polymer particles; When loading, the servo motor 4 is started to drive the driving roller 15 to reverse, and the linkage folding rod 29 is driven to rise and fall and vibrate under the cooperation of the incomplete gear 32 and the vibrating tooth plate 33. If the polymer particles in the left storage box 7 need to be discharged, the linkage mechanism on the left can be started, and if the polymer particles on the right need to be discharged, the linkage mechanism on the right is started. If both discharges are required, the two linkage mechanisms are started at the same time. When the linkage folding rod 29 is lifted and vibrated, it drives the screening filter 28 to be lifted and vibrated with the cooperation of the linkage mechanism, so that when the screening filter 28 vibrates, the polymer particles on it will gradually vibrate and slide from the left side to the right side. When the good polymer particles slide to the rightmost side, they will fall into the guide tube 8 and fall into the weighing bucket 9 through the guide tube 8. At this time, the weighing bucket 9 will accurately weigh the weight of the polymer particles. When the weighed weight meets the discharge requirement, the guide tube 8 is closed to stop the discharge, and then the feeding tube 5 is opened to guide the quantitative polymer particles in the weighing bucket 9, thereby realizing the accurate measurement and discharge of the polymer particles.

Pour the polymer granular material into the storage component through the feeding component for storage; S2. When feeding, the polymer granular material is color-sorted by the color sorting component and then color-sorted and screened according to the color difference; S3, during the color sorting and screening process, the slag removal component is used to remove the broken slag; S4.
