Description

Technical Field

[0001] This utility model relates to the field of screening and packaging equipment technology, and in particular to a resin particle screening and packaging equipment. Background Technology

[0002] Resin particles refer to small granular substances made of resin materials. Resin is an organic polymer compound with good adhesion, chemical resistance and mechanical properties.

[0003] Resin particles can be modified with modifiers, fillers, and additives to impart specific functions to materials. For example, Chinese Patent Publication No. CN214211275U provides a molding and screening system for phenolic resin, belonging to the field of screening equipment technology. This molding and screening system for phenolic resin includes a support assembly, a screening assembly, and a feeding assembly. The support assembly includes a support plate, a support column, a shock-absorbing spring, a second horizontal plate, a first discharge pipe, a reaction vessel, a first feed pipe, a second feed pipe, a hose, a flange, and a second discharge pipe. The support column is fixed to the upper surface of the support plate. In use, the rotation of the output shaft of the first motor drives the chain drive component to rotate, which in turn drives the connecting shaft to rotate. The rotation of the connecting shaft drives the grinding block to rotate. Under the combined action of the grinding block and the wear-resistant steel block, the phenolic resin is ground into particles of the required size. This screening system facilitates the direct processing of phenolic resin that does not meet the requirements, improving the processing efficiency of phenolic resin with non-compliant particle sizes.

[0004] Currently, when resin granules are used as an auxiliary material in product manufacturing, they need to be screened to ensure that the size of each particle is basically the same. Due to the long-term storage of resin granules, fine impurity particles will be mixed in. At the same time, due to the influence of ambient temperature, some resin granules will oxidize and stick together. Therefore, it is necessary to screen the resin granules before they are put into use. After screening, stable discharge is also required to facilitate subsequent packaging and storage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4A resin particle screening and packaging device includes a base 1, a box 11 fixed above the base 1 by a bracket, the box 11 is a rectangular box structure, which can serve as a material container during screening, a cover plate 12 is fixed at the upper end of the box 11, the lower end of the box 11 is an open area, and a ramp 13 corresponding to the position of the box 11 is fixed at the upper end of the base 1. The ramp 13 can guide the fine particle impurities that fall down after screening through the screening holes 18 of the screening plate 17 to slide down and be collected in a concentrated manner. The inclined groove of the ramp 13 corresponds to the open area of ​​the box 11.

[0027] The upper end of the cover plate 12 is fixedly connected to the feed port 14, which is a rectangular structure. The feed port 14 is embedded with a grid 15, which is composed of round rods with intersecting warp and weft. The grid 15 is mainly used to screen resin particles that are clumped or have an oversized volume, so as to avoid affecting the efficiency of subsequent mixing and melting.

[0028] A screening port 16 is provided on one side of the box body 11. A screening plate 17 is slidably attached to the inner wall of the box body 11. Several screening holes 18 are provided on the surface of the screening plate 17. Two symmetrically distributed guide blocks 19 are fixed at the upper end of the screening plate 17. The narrow opening of the guide block 19 corresponds to the position of the screening port 16. The screening plate 17 is inclined, and the lower end of the inclined position corresponds to the position of the screening port 16. The inclined setting of the screening plate 17 can play a material guiding effect when filtering resin particles. At the same time, fine impurities smaller than the screening holes 18 can be filtered out through the screening port 16.

[0029] It should be further explained that a guide post 21 is fixed at the lower end of the screening plate 17, and a guide sleeve 2 is slidably sleeved on the surface of the guide post 21. The outer ring wall of the guide sleeve 2 is fixedly assembled with the inside of the box 11. An anti-detachment block 22 is fixed at the lower end of the guide post 21. The anti-detachment block 22 can support the compression and reset of the spring 23, ensuring the stability of the position of the spring 23 during the extension and retraction process.

[0030] It should be further explained that a spring 23 is wound around the surface of the guide column 21. The two ends of the spring 23 are fixedly assembled to the surface of the anti-detachment block 22 and the end face of the guide sleeve 2, respectively. There are two sets of springs 23, which correspond to the high and low positions of the screening plate 17. The guide column 21 can slide up and down in the guide sleeve 2 and drive the screening plate 17 to move up and down relative to the inner wall of the box 11. Thus, the vibration screening of resin particles can be realized. The spring 23 can achieve the effect of extension and resetting during this vibration process.

[0031] It should be further explained that a motor 2001 is installed inside the housing 11. The outer wall of the motor 2001 is fixedly mounted to the inner wall of the housing 11 via a bracket. A drive shaft is installed inside the motor 2001. An eccentric wheel 2002 is fixed to the end of the drive shaft. The height of the eccentric wheel 2002 is always in contact with the lower end face of the screening plate 17. When vibratory screening is required, the power supply to the motor 2001 is turned on, so that the drive shaft of the motor 2001 can drive the eccentric wheel 2002 to rotate. Thus, the height of the eccentric wheel 2002 continuously alternates with the screening plate 17, realizing the lifting and releasing, and continuous alternating movement. The screening plate 17 has a vibration effect, which can realize the screening of resin particles.

[0032] It should be further explained that a feeding channel 3 is provided at one end of the box body 11. The opening end of the feeding channel 3 covers the port position of the screening port 16. The outer wall of the feeding channel 3 is fixed to the surface of the box body 11 by a bracket. The lower end of the feeding channel 3 is fixedly provided with a discharge port 31 on the side away from the box body 11. After the resin particles that meet the specifications are screened out, they can enter the feeding channel 3 through the screening port 16 to wait for the resin feeding in the packaging process.

[0033] It should be further explained that a bearing 32 is fixedly inserted through the closed end of the feeding channel 3, and a shaft 33 is inserted through the inside of the bearing 32. The surface of the shaft 33 is interference-fitted with the inner ring wall of the bearing 32, and the shaft 33 can rotate stably based on the bearing 32.

[0034] It should be further explained that a spiral blade 34 is wound around the surface of the shaft 33. The outer spiral surface of the spiral blade 34 is closely attached to the inner wall of the feeding channel 3. The spiral blade 34 can enter the feeding channel 3 after the resin particles are discharged through the screening port 16. The spiral blade 34 can realize the spiral feeding of the resin particles. The purpose of spiral feeding is to provide quantitative feeding during packaging, keep the resin particles discharged at a uniform speed, and avoid a rush of resin particles that may spill out.

[0035] It should be further explained that a second motor 35 is provided at the outer end of the shaft 33. The outer wall of the second motor 35 is fixedly assembled with the surface of the feeding channel 3 through a bracket. The second motor 35 is provided with a second rotating shaft for driving. The end of the second rotating shaft is fixedly connected to the end of the shaft 33 through a coupling. The second motor 35 can drive the second rotating shaft to drive it, so that the second rotating shaft can rotate the spiral blade 34, realizing stable spiral feeding based on the feeding channel 3. Finally, when the resin particles reach the discharge interface 31, they fall directly and are discharged.

[0036] Working method: This solution achieves effective separation of resin particles and impurities through a vibrating screening mechanism. Resin particles enter the box 11 from the feed inlet 14 and are first screened by the grid 15. Agglomerates or oversized particles are intercepted to ensure the uniformity of subsequent processing. The screening plate 17 is inclined inside the box 11, and its surface is densely covered with screening holes 18. The motor 2001 drives the eccentric wheel 2002 to rotate, periodically lifting the bottom of the screening plate 17. With the elastic reset of the spring 23, the screening plate 17 generates high-frequency vibration. During the vibration, resin particles that meet the specifications slide along the inclined surface to the screening port 16 because their particle size is larger than the screening holes 18, while fine impurities fall into the inclined groove of the ramp 13 through the screening holes 18 and are finally collected. This process significantly improves screening efficiency through the synergistic effect of mechanical vibration and gravity separation, while avoiding the problem of easy clogging of traditional static screens.

[0037] After screening, qualified resin particles enter the feeding channel 3 through the screening port 16. The screw conveyor mechanism achieves quantitative discharge. The motor 35 drives the shaft 33 to rotate, which in turn drives the screw blade 34 to rotate at a constant speed in the feeding channel 3. The resin particles move along the channel axis under the push of the screw blade 34. The conveying speed is precisely controlled by the motor speed to ensure that the discharge amount at the discharge port 31 is uniform and stable. The screw feeding design avoids the accumulation or splashing of particles due to gravity free fall, which is especially suitable for automated packaging. In addition, the tight fit between the screw blade 34 and the inner wall of the channel effectively prevents the particles from flowing back and ensures the continuity of conveying.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
