Description

Technical Field

[0001] The invention belongs to the technical field of resin processing, and in particular relates to a feeding device for resin processing. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid or powdery at room temperature. During the compounding process, the powdered resin needs to be fed into a mixer.

[0003] At present, the following two types of feeders are often used in this processing procedure to convey solid powdered materials: vacuum feeder and auger-type feeder. The defects of using vacuum feeder in the processing procedure of powdered PVB resin compounding materials are obvious. Since the material is in powdery form, the vacuum bag is easily blocked, and the conveying effect is greatly reduced. There is also an auger-type feeder, which is a full-metal structure. The particles of chloroether resin are fine and have strong adhesion to metal pipelines. It is easy to cause the material to accumulate in the acceleration chamber and the conveying pipeline, blocking the conveying pipeline. There is also a height difference between the discharge end of the auger-type feeder and the transportation device. Since the resin particles are fine, dust will be flying when the material is discharged to the surface of the transportation device, which poses certain production safety risks.

[0019] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0020] 1. By setting a feeding anti-blocking component, and by using the fixed legs, adjusting brackets, rotating frame, wedges and fixed support frames, the rotating frame can be rotated during feeding, and the wedges can intermittently push the adjusting brackets, so that the adjusting brackets can slide back and forth in the fixed legs, and then the feeding hopper can slide up and down reciprocatingly during the discharge process, so that the feeding hopper vibrates, avoiding the eddy current phenomenon of the resin material in the pipeline during the feeding process, preventing the conveying pipeline from being blocked, effectively improving the fluidity of the resin material, and achieving a uniform and smooth feeding effect;

[0021] Through the setting of the inclined surface of the wedge block, it slides into the slide groove provided on the surface of the adjusting bracket, so that the adjusting bracket can be pushed up and down to drive the upper hopper to shake up and down, so as to reduce the resistance;

[0022] Through the cooperation of a sliding protrusion integrally formed at one end of the adjusting bracket and a strip groove provided in the fixed leg, the adjusting bracket can slide in the fixed leg so that the adjusting bracket can be limited in position during the up and down shaking of the upper hopper to prevent the adjusting bracket from slipping off;

[0023] By cooperating with the support slide bar and the annular groove, the rotating frame can be rotated so that when the wedge block on its surface pushes the upper hopper through the adjusting bracket, the support slide bar can slide in the annular groove. At the same time, the number of support slide bars and wedge blocks is the same and their positions are relative, so that the rotating frame can be rotationally guided and supported, to ensure that the upper hopper can shake stably when unloading materials, thereby improving the feeding effect.

[0024] 2. By setting a material flow assembly, and by using the coordinated use of the gear ring, gear, T-bar, connecting sleeve, lever, lever post and spiral pushing piece and other structures, when the upper hopper is shaken to discharge materials, the lever can rotate around the connecting sleeve, and when the lever contacts the lever post fixed on the surface of the rotating sealing cover, the rotating sealing cover can rotate on the surface of the upper hopper, and at the same time, a plurality of spiral pushing pieces installed on the bottom surface of the rotating sealing cover can rotate in the upper hopper to disperse the resin material in the upper hopper and avoid the accumulation and hardening of the material. At the same time, during the feeding process of the upper hopper, the setting of a plurality of spiral pushing pieces can also play a role of spiral pushing on the resin material in the upper hopper, so as to promote the resin material to be discharged smoothly and fluently from the discharge pipe at the bottom of the upper hopper after being pressed to perform the feeding action, so as to ensure the feeding stability;

[0025] When the rotary sealing cover rotates, it can cause the L-shaped rod slidably connected to its surface to rotate along with it, so that the spiral dispersing piece can rotate along with it, and the resin material in the upper hopper can be dispersed again. The spiral dispersing piece arranged in the opposite spiral direction can cause the resin material in the upper hopper to collide and convection, so as to ensure the uniformity of the resin material and avoid the resin material agglomerating and clogging the pipeline when feeding, so as to improve the feeding effect;

[0026] When the L-shaped rod rotates, it is limited to a fixed height, and the position of the upper hopper is in a state of shaking up and down. At this time, the position of the spiral stirring piece fixed at one end of the L-shaped rod in the upper hopper can change accordingly, so as to further improve the uniformity of the resin material and ensure the turning effect of the resin material and the smoothness of the feeding.

[0027] 3. By setting up a feeding anti-blocking component, and by using the coordinated structures such as the conical blocking disk, the connecting hollow rod, the sliding rod, the scraper bar and the L-shaped supporting connector, when it is necessary to control the feeding, the conical blocking disk is moved upward in the feeding hopper by controlling the hydraulic rod, and the discharge pipe at the bottom of the feeding hopper is opened, so as to realize uniform feeding of the resin material in the feeding hopper;

[0028] When the conical sealing disk moves up to feed materials or moves down to seal the discharge pipe, it can drive the connecting hollow rod fixed at the bottom of the conical sealing disk to move along with it. Through the cooperation of the sliding protrusions integrally formed in the connecting hollow rod and the spiral grooves provided on the outer side of the sliding rod, the connecting hollow rod can follow the up and down movement, so that the sliding rod together with the L-shaped supporting connecting piece can rotate in the discharge pipe of the upper hopper, and then the scraper on the surface of the L-shaped supporting connecting piece can follow the rotation, so as to realize the cleaning of the inner wall of the discharge pipe, prevent the inner wall of the discharge pipe from being blocked due to long-term use, and ensure the smooth feeding of the resin material.

[0029] At the same time, the dust hood and the one-way reflux pipe are arranged in coordination, so that during the loading process, the dust hood can absorb the powdered resin material floating on the falling conveyor belt, and transport the resin material to the upper hopper again through the one-way reflux pipe. The filter plate arranged in coordination can filter the blown gas in one direction, so that the resin material falls into the upper hopper, and the gas can be blown out from the upper hopper. In addition, the shaking method can also prevent the filter plate from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] A connecting hollow rod 44 is fixed to the bottom of the conical sealing disk 43, and a sliding rod 45 is slidably connected inside the connecting hollow rod 44. A sliding protrusion 49 is integrally formed on the inner wall of the connecting hollow rod 44, and a spiral groove 48 is provided on the surface of the sliding rod 45.

The L-shaped structure of the L-shaped supporting connector 47 is slidably connected in an annular groove provided on the outer side of the bottom of the upper hopper 1. A scraper strip 46 is fixed to the surface of the L-shaped supporting connector 47, and the scraper strip 46 fits against the inner wall of the discharge pipe at the bottom of the upper hopper 1.

[0060] A dust hood 410 is fixed to the outside of the discharge pipe at the bottom of the upper hopper 1. The surface of the dust hood 410 is connected to a one-way return pipe 411. One end of the one-way return pipe 411 is connected to the upper hopper 1. A filter plate 412 is installed on the surface of the rotating sealing cover 38.

[0061] The working principle and use process of the present invention: When the feeding device is in use, it is necessary to ensure that there is a sufficient amount of powdered resin material in the feeding hopper 1, and turn on the conveyor belt 11, and then control the opening and closing of the discharge pipe so that the resin material in the feeding hopper 1 is poured into the surface of the conveyor belt 11 through the discharge pipe, and the conveyor belt 11 is used to feed the resin material. When feeding, the servo motor 27 can be controlled to start, so that the rotating frame 28 installed on the output shaft of the servo motor 27 can rotate, and then the rotating frame 28 can drive the wedge block 29 to follow the movement, and make the wedge block 29 intermittently push the adjustment bracket 24. At this time, the adjustment bracket 24 can slide reciprocatingly in the fixed leg 21, and then the feeding hopper 1 can slide reciprocatingly up and down during the discharging process, so that the feeding hopper 1 vibrates, avoiding the eddy current phenomenon of the resin material in the pipeline during the feeding process, preventing the conveying pipeline from being blocked, effectively improving the fluidity of the resin material, and achieving a uniform and smooth feeding effect;

[0062] Through the setting of the inclined surface of the wedge block 29, it slides into the slide groove opened on the surface of the adjustment bracket 24, so that the adjustment bracket 24 can be pushed up and down to drive the upper hopper 1 to shake up and down, so as to reduce resistance;

[0063] By using the sliding protrusion 26 integrally formed at one end of the adjusting bracket 24 and the strip groove 25 provided in the fixed leg 21, the adjusting bracket 24 can slide in the fixed leg 21, so that the adjusting bracket 24 can be limited in position during the up and down shaking of the upper hopper 1 to prevent the adjusting bracket 24 from slipping off;

[0064] The supporting slide bar 211 and the annular groove 23 are arranged in cooperation so that the rotating frame 28 can rotate, so that when the wedge block 29 on its surface pushes the upper hopper 1 through the adjusting bracket 24, the supporting slide bar 211 can slide in the annular groove 23. At the same time, the supporting slide bar 211 and the wedge block 29 are the same in number and relative in position, so that the rotating frame 28 can be rotationally guided and supported, so as to ensure that the upper hopper 1 can shake stably when unloading materials, thereby improving the feeding effect;

[0065] When the rotating frame 28 rotates, the gear ring 31 on its outer side can drive the gear 32 to rotate, thereby prompting the T-shaped rod 33 rotating on the surface of the fixed plate 22 to rotate. When the T-shaped rod 33 rotates, the connecting sleeve 35 and the lever 36 fixed on the surface of the connecting sleeve 35 can follow the rotation. Then, when the lever 36 rotates around the connecting sleeve 35, the lever 36 contacts the lever 37 fixed on the surface of the rotating sealing cover 38, so that the rotating sealing cover 38 can rotate on the surface of the upper hopper 1. At the same time, a plurality of spiral pushing members 39 installed on the bottom surface of the rotating sealing cover 38 can rotate in the upper hopper 1 to disperse the resin material in the upper hopper 1 to avoid the accumulation and hardening of the material. At the same time, during the feeding process of the upper hopper 1, the setting of the plurality of spiral pushing members 39 can also play a spiral pushing role on the resin material in the upper hopper 1, so as to promote the resin material to be smoothly and fluently discharged from the discharge pipe at the bottom of the upper hopper 1 after being pressed to perform the feeding action, so as to ensure the feeding stability.

[0066] When the rotary sealing cover 38 rotates, it can cause the L-shaped rod 314 slidably connected to its surface to rotate along with it, so that the spiral dispersing member 315 can rotate along with it, and can disperse the resin material in the upper hopper 1 again. The spiral dispersing member 315 arranged in the opposite spiral direction can cause the resin material in the upper hopper 1 to collide and convection, so as to ensure the uniformity of the resin material and avoid the resin material from agglomerating and clogging the pipeline when feeding, so as to improve the feeding effect;

[0067] When the L-shaped rod 314 is rotated, it is limited to a fixed height by the slider 313, the fixed slide 312 and the support plate 311, and the position of the upper hopper 1 is in a state of shaking up and down. At this time, the position of the spiral stirring member 315 fixed at one end of the L-shaped rod 314 in the upper hopper 1 can be changed accordingly, so as to further improve the uniformity of the resin material, ensure the turning effect of the resin material and the smoothness of the feeding;

[0068] When it is necessary to control the feeding, the hydraulic rod 41 is controlled so that the hydraulic rod 41 drives the conical blocking plate 43 to move upward in the upper hopper 1 through the connecting rod 42, and the discharge pipe at the bottom of the upper hopper 1 is opened, and the above-mentioned use process is cooperated to realize uniform feeding of the resin material in the upper hopper 1;

[0069] When the conical sealing disk 43 moves up to feed materials or moves down to seal the discharge pipe, it can drive the connecting hollow rod 44 fixed at the bottom of the conical sealing disk 43 to follow the movement. Through the cooperation of the sliding protrusion 49 integrally formed in the connecting hollow rod 44 and the spiral groove 48 provided on the outer side of the sliding rod 45, the connecting hollow rod 44 can follow the up and down movement, so that the sliding rod 45 and the L-shaped supporting connecting piece 47 can rotate in the discharge pipe of the upper hopper 1, and then the scraper 46 on the surface of the L-shaped supporting connecting piece 47 can follow the rotation, so as to realize the cleaning of the inner wall of the discharge pipe, prevent the inner wall of the discharge pipe from being blocked due to long-term use, and ensure the smooth feeding of the resin material.

[0070] At the same time, by cooperating with the dust hood 410 and the one-way return pipe 411, during the loading process, the dust hood 410 can absorb the powdered resin material floating on the falling conveyor belt 11, and transport the resin material back to the upper hopper 1 through the one-way return pipe 411. The filter plate 412 can filter the blown gas in one direction, so that the resin material falls into the upper hopper 1, and the gas can be blown out from the upper hopper 1. In addition, by shaking, the filter plate 412 can also be prevented from being blocked.

[0071] It should be noted that the one-way return pipe 411 is a detachable structure, so that the one-way return pipe 411 can be disassembled, cleaned and replaced according to usage.

[0072] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
