Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Example 1

A vibrating screening device for plastic particle production and processing, as shown in Figure 1-14, includes a vibrating screen 1, a first mounting frame 2, a screening system and a drying system; the left side of the vibrating screen 1 is bolted to the first mounting frame 2. There are two oblique grooves 1a on the lower side of each hole of the screen in the vibrating screen 1; the vibrating screen 1 is connected to a screening system; the first installation frame 2 is connected to a drying system; the screening system restricts the passage of nylon particles The length in the vibrating sieve 1, thereby avoiding that when the overlong nylon particles are consistent with the size of the screen hole of the vibrating sieve 1, the overlong nylon granules enter the qualified nylon granules through the sieve of the vibrating sieve 1.

Existing screening equipment usually limits the size of the screen holes, and then screens out unqualified nylon particles and qualified nylon particles, and when the size of the overlong nylon particles is consistent with the size of the screen holes, the overlong nylon particles pass through. The sieve mesh enters the qualified nylon granules, aiming at this, the present invention proposes a vibrating screening equipment for the production and processing of plastic granules;

During the work of the present invention, the nylon granules that have been cut are sent to the drying system by the previous production line, and then transferred to the vibrating screen 1 by the drying system for screening. In this process, when the nylon granules are sent to the drying system , the drying system seals the nylon particles in a rotating manner. During this process, when the drying system seals the nylon particles, a sealed area is formed, and then the blocked nylon particles are dried in the form of hot air. At this time, since the blocked nylon particles are in a sealed space, the drying speed can be accelerated. At the same time, the nylon particles are stirred by the drying system to drive the nylon particles to rotate irregularly, and then switch the receiving surface of the nylon particles, and At the same time, the gap between the nylon particles is increased by warping, so as to avoid the tight fit between the nylon particles, which will lead to insufficient heating of the upper nylon particles. When the drying system unblocks the nylon particles , the nylon particles move down by their own weight, and are transferred to the vibrating screen 1 for screening. During this process, the nylon particles moving down are collided by the drying system in a rotating manner, and then the bonded nylon particles are Separation, and through the way of collision, the powder attached to the surface of the nylon particles is separated from the surface of the nylon particles. During this process, the drying system will absorb the air in the sealed area to perform gas replacement. During this process, the drying The dry system filters the air in the sealed area by means of filtration, so as to avoid the presence of powder in the air in the sealed area, which will affect the health of the artificial body. At the same time, during the gas replacement process of the drying system, the drying system uses The suction method collects the powder detached from the surface of the nylon particles, so as to avoid the surface of the screened nylon particles still attached to a large amount of powder, which requires subsequent repeated screening;

When the nylon particles are transferred to the vibrating screen 1, the vibrating motor in the vibrating screen 1 is used to vibrate, so that the nylon particles fall through the holes in the screen of the vibrating screen 1 to the screening system. The meshes in the sieve 1 cooperate with each other to form a restriction. When the length of the nylon particles is too long, it will be restricted by the restriction formed by the cooperation between the screening system and the mesh in the vibrating screen 1, and will be stuck in the holes of the mesh in the vibrating screen 1. Then, the nylon particles are pushed down by means of pressure through the screening system, and then judge whether the nylon particles stuck on the holes of the screen in the vibrating screen 1 are too long at this time, and when the nylon particles stuck in the holes of the screen in When the nylon particles on the holes are of qualified length, they can be pushed down, thereby reducing the clogging phenomenon, thereby accelerating the filtration efficiency, and when the nylon particles stuck on the holes of the screen in the vibrating screen 1 are too long, the screening system will It is impossible to push it down, and then cut the overlong nylon particles through the screening system, so as to prevent the overlong nylon particles from entering the qualified nylon particles through the screen;

The invention uses the drying system to seal the gaps of the nylon particles in a rotating manner. When the drying system seals the nylon particles, a sealing area is formed, and then the blocked nylon particles are dried in the form of hot air. If the particles are in a sealed space, the drying speed can be accelerated;

Stir the nylon particles through the drying system to drive the nylon particles to rotate irregularly, and then switch the receiving surface of the nylon particles. At the same time, increase the gap between the nylon particles by warping to avoid the tightness between the nylon particles The fit together, resulting in insufficient heating of the upper nylon particles;

Through the drying system, the nylon particles moving down are collided in a rotating manner, and then the bonded nylon particles are separated, and the powder attached to the surface of the nylon particles is separated from the surface of the nylon particles by means of collision. The air in the sealed area is absorbed by the drying system to perform gas replacement. During this process, the drying system filters the air in the sealed area by filtering;

The powder detached from the surface of the nylon particles is collected by suction through the drying system, so as to avoid the surface of the screened nylon particles still attached to a large amount of powder, which requires subsequent repeated screening;

The screening system cooperates with the screen in the vibrating screen 1 to form a restriction. When the length of the nylon particles is too long, it will be restricted by the restriction formed by the cooperation between the screening system and the screen in the vibrating screen 1 and get stuck in the vibrating screen 1. Then the nylon particles are pushed down by means of pressure through the screening system to judge whether the nylon particles stuck on the holes of the middle screen of the vibrating screen 1 are too long at this time, and when they are stuck on the vibrating screen When the nylon particles on the holes of the screen in vibrating screen 1 are of qualified length, they can be pushed down, thereby reducing clogging and accelerating the filtration efficiency.

The joints between the two triangular plates 2010 can increase the sealing performance between the four first triangular plates 208 and the four second triangular plates 2010, since the first scraper 2011 and the second scraper 235 are made of air-permeable steel, and thus To avoid the influence of heat when drying the nylon particles, which will cause the first scraper 2011 and the second scraper 235 to deform, and lose the sealing between the four first triangular plates 208 and the four second triangular plates 2010 At the same time, the external heating device transfers the hot air to the air delivery pipe 205 through the air inlet pipe 206, and then transfers the hot air to the corresponding second through holes 207a and third through the four first through holes 205a in turn. In the through hole 208a, then transfer to two first hollow stirring plates 210 and the second hollow stirring plate 220 corresponding to it through four third through holes 208a, then pass through eight first hollow stirring plates 210 with Several first air outlet holes 210a and several second air outlet holes 220a on the four second pushing plates 221 are used to dry the blocked nylon particles in the form of hot air. If the particles are in a sealed space, the drying speed can be accelerated;

It should be noted that during this process, eight first hollow stirring plates 210, four second pushing plates 221, several first pushing plates 211 and several second pushing plates 221 will stir the nylon particles, driving the nylon particles to The particles rotate irregularly, and then switch the heating surface of the nylon particles. At the same time, when several first push plates 211 and several second push plates 221 contact with their corresponding limit blocks 234, they are affected by the force of several limit blocks 234 Limitation, several first push plates 211 and several second push plates 221 will rotate, and then move the nylon particles upward, and then increase the gap between the nylon particles in a warped manner, thereby avoiding the tight contact between the nylon particles When the four first triangular plates 208 are located directly above the corresponding second triangular plates 2010, the four first triangular plates 208 and the four second triangular plates 2010 are released. For the plugging of nylon particles, the nylon particles move down through the discharge area 2010a and are transferred to the vibrating screen 1 for screening;

It should be noted that when the first motor 204 drives the four first triangular plates 208 to rotate, when the eight first hollow agitating plates 210 touch the corresponding second triangular plates 2010, the eight first scrapers 2011 will scrape the nylon particles on the surface of the second triangular plate 2010 corresponding to it, thereby preventing the nylon particles from being bonded to the second triangular plate 2010 after heating. At the same time, when the four first triangular plates 208 contact the corresponding second triangular plate When the scraper 235 is used, eight second scrapers 235 are used to scrape the nylon particles on the surface of the first triangular plate 208 corresponding to it, so as to prevent the nylon particles from being bonded to the first triangular plate 208 after being heated;

It should be noted that when the four first triangular plates 208 and the four second triangular plates 2010 unblock the nylon particles, the nylon particles move downward through the discharge area 2010a and are transferred to the vibrating screen 1. When the nylon particles When the particles touch the stirrer 245, the second motor 244 installed on the fourth mounting plate 243 drives the stirrer 245 to rotate continuously, and then when the nylon particles contact the stirrer 245, the nylon particles collide with the stirrer 245 , so as to collide with the nylon particles moving down, and then separate the bonded nylon particles, and through the collision, the powder attached to the surface of the nylon particles is separated from the surface of the nylon particles. In this process, through The aspirator 246 absorbs the air in the sealing area formed by the mutual cooperation of the four first triangular plates 208 and the four second triangular plates 2010 and the pipe 201, transfers it to the installation cover 241, and then transfers it to the installation cover 241 through the filter screen 247 The outside is used for gas replacement. During this process, the inside of the filter 247 is provided with activated carbon cotton, which can better filter the air in the sealed area, thereby avoiding the presence of powder in the air in the sealed area, which will affect the health of the artificial body. At the same time, during the gas replacement process of the air aspirator 246, the air aspirator 246 collects the powder detached from the surface of the nylon particles by suction, thereby avoiding that the surface of the screened nylon particles is still attached to a large amount of powder, which requires follow-up Repeated screening, during this process, the four isolation nets 242 play the role of isolation, thereby preventing the transfer of nylon particles to the inside of the installation cover 241;

When the nylon particles are transferred to the vibrating screen 1, the vibrating motor in the vibrating screen 1 is used to vibrate, so that the nylon particles fall through the holes in the screen mesh of the vibrating screen 1 to the restricting plate 111, and then flow out through the inclined plate 112, In this process, the restricting plate 111 cooperates with the screen in the vibrating screen 1 to form restrictions. When the nylon particles passing through the holes in the screen in the vibrating screen 1 are of qualified length, they will not be restricted by the restricting plate 111 and the screen in the vibrating screen 1. Restricted by the middle screen, it can flow out directly through the inclined plate 112. When the length of the nylon particles is too long, it will be restricted by the restriction formed by the cooperation between the restricting plate 111 and the screen in the vibrating screen 1, and it will be stuck in the vibrating screen. At the same time, the two moving blocks 102 installed on the two guide rails 101 drive the two moving blocks 102 and all the parts connected to it to move repeatedly left and right. In this process, when the two guide rails 101 When a moving block 102 drives and all the parts connected to it move to the right, when several slide plates 122 on the right side touch the nylon particles stuck on the holes of the screen mesh in the vibrating screen 1, they are limited by the nylon particles. The sliding plate 122 corresponding to the nylon particles stuck on the holes of the screen mesh in the vibrating screen 1 moves to the left, and the spring 123 is in a compressed state at this time. The push rod 126 rotates obliquely downward under the drive of the torsion spring, so as to push the nylon particles stuck on the holes of the screen mesh in the vibrating screen 1 to move downward in a pressing manner, and then judge that the nylon particles stuck in the vibrating screen 1 are judged at this time. Whether the nylon particles on the holes of the screen are too long, and when the nylon particles stuck on the holes of the screen in the vibrating screen 1 are of qualified length, they can be pushed down, thereby reducing the clogging phenomenon and accelerating the filtration efficiency , and when the nylon particles stuck on the holes of the screen mesh in the vibrating screen 1 are too long, the arc push rod 126 cannot push it down, and the arc push rod 126 is made of steel, thereby avoiding the arc push rod 126 When pushing the nylon particles stuck in the holes of the screen mesh on the vibrating screen 1, deformation occurs, which affects the pushing effect of the arc push rod 126, and then when the overlong nylon particles stuck on the holes of the screen mesh in the vibrating screen 1 When the corresponding cutting knife 129 contacts, the cutting knife 129 will cut the overlong nylon particles stuck on the holes of the screen in the vibrating screen 1 and then cut them into two sections, one section is stuck between the restricting plate 111 and the screen in the vibrating screen 1 In between, the other section stays on the surface of the screen in the vibrating screen 1, and during this process, the nylon particles stuck between the limiting plate 111 and the screen in the vibrating screen 1 are continuously vibrated by the vibrating motor in the vibrating screen 1. By offsetting the two oblique grooves 1a corresponding to it, the restriction of mutual cooperation between the restricting plate 111 and the screen in the vibrating screen 1 is released, and the restriction falls to the restricting plate 111, and then the inclined plate 112 flows out, thereby avoiding excessive length The nylon granules pass through the sieve and enter the qualified nylon granules, while the nylon granules that stay on the surface of the sieve in the vibrating screen 1 continue to be screened in the above-mentioned way;

When the two moving blocks 102 on the two guide rails 101 drive and all the parts connected thereto move to the left, the nylon granules stuck on the holes of the screen cloth in the vibrating screen 1 are cut by the above method.

Those skilled in the industry should understand that the above-mentioned embodiments do not limit the present invention in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
