Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a particle collecting device for plastic particle production. Background Art

[0002] Plastic granules are a product made of resin materials. The resin materials are made into granules through a specific production process and are then widely used in various plastic products. There are many types of plastic granules. The common plastics we see are generally general-purpose plastics, which are also one of the most widely used plastics.

[0003] Plastic particles are collected by a plastic collecting device during the production process. In the prior art, the Chinese patent CN215202922U is titled "A particle collecting device for plastic particle production." This prior art solves the problem of screening particles of different sizes. However, we found that in this technology, plastic particles are easily accumulated when entering the baffle plate for screening. When multiple layers of plastic particles pass through the baffle plate, only the plastic particles at the bottom layer are screened out. Even if the upper plastic particles can pass through the screening at this position, it is difficult to be screened down. Therefore, they roll to the next sieve hole on the baffle plate and then fall from the sieve hole, causing different particles to be mixed and collected, resulting in less than ideal screening effect.

[0004] Therefore, how to provide a particle collection device for plastic particle production is an urgent problem that those skilled in the art need to solve. Utility Model Content

The top end of the second spring component is in contact with the lower surface of the block, and the bottom end of the second spring component is in contact with the upper surface of the screening plate.

[0008] The vibration motor is located in the middle of the line connecting the two groups of guide rods.

[0009] A first spring member is fixed to the upper surface of the second fixing plate, and the first spring member is movably attached to the upper surface of the screening plate.

[0010] The upper surface of the screening plate is also provided with a distribution assembly, which includes three groups of material distribution assemblies, and the material distribution assembly includes a fixed seat, the fixed seat is fixed to the upper surface of the screening plate, and a cross bar parallel to the screening plate is provided on the fixed seat away from the screening plate. The surface of the cross bar is movably sleeved with a dial tube, and the surface of the dial tube is provided with a dial rod near the screening plate.

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] Example 1

[0024] refer to Figure 1 and Figure 2, including a collecting box 1 and a screening plate 2, the screening plate 2 is tilted and movable inside the collecting box 1, and a collecting chamber 3 is provided inside the collecting box 1. The number and position of the collecting chamber 3 correspond to the number and position on the screening plate 2, ensuring that the screened plastic particles enter the corresponding collecting chamber 3, and a plurality of groups of screening holes are provided on the screening plate 2. The diameter of the screening holes close to the upturned end of the screening plate 2 is short, and the diameter of the screening holes gradually increases as they approach the downward inclined end of the screening holes, so that the plastic particles can be accurately screened. It should be noted that the number of screening holes on the screening plate 2 is three groups, which are used to screen four plastic particles with different diameters, and the number of groups of screening holes is set according to the plastic particles with different diameters actually screened;

[0025] refer to Figure 2 、 Figure 3 and Figure 4The inner wall of the collection box 1 is located above the collection chamber 3 and corresponds to the two ends of the screening plate 2, and is respectively fixed with a first fixed plate 4 and a second fixed plate 5. The first fixed plate 4 is located at the downwardly inclined end of the screening plate 2, and the second fixed plate 5 is located at the upwardly tilted end of the screening plate 2. A guide assembly 6 is provided on the top of the first fixed plate 4, and the guide assembly 6 includes two groups of guide rods 8. The two groups of guide rods 8 are vertical and axially symmetrically arranged on the screening plate 2 with the symmetry axis of the screening plate 2 as the symmetry axis. In this way, in order to make the screening plate 2 balanced in force and more stable in activity, the two groups of guide rods 8 are fixed on the upper surface of the first fixed plate 4 and located at the vibration motor. 7, the top ends of the two groups of guide rods 8 pass through the screen plate 2 and extend to the top of the screen plate 2. The top ends of the two groups of guide rods 8 are fixed with blocks 9, which are used to block the second spring member 10. The two groups of guide rods 8 are located on the surface above the screen plate 2 and are movably sleeved with the second spring member 10. The top end of the second spring member 10 is attached to the lower surface of the block 9, and the bottom end of the second spring member 10 is attached to the upper surface of the screen plate 2. The screen plate 2 is movably sleeved on the surface of the guide assembly 6. When the screen plate 2 is active, the screen plate 2 has a downward force through the second spring member 10, so that the screen plate 2 returns to its original position faster, so that the screen plate 2 The shaking effect is better. A vibration motor 7 is fixed on the upper surface of the first fixed plate 4. The output shaft of the vibration motor 7 is attached to the lower surface of the screen plate 2. The vibration motor 7 is located in the middle position of the connection line of the two sets of guide rods 8. The middle position setting can make the end of the screen plate 2 balanced when vibrating, so that it can move up and down stably on the guide rod 8. A first spring member 11 is fixed on the upper surface of the second fixed plate 5. The first spring member 11 is movably attached to the upper surface of the screen plate 2. The first spring member 11 is attached to the lower surface of the screen plate 2 near the upturned end, and when the screen plate 2 falls, it gives the screen plate 2 an upward position after reaching the final position. The force is applied to stabilize the end face of the screening plate 2 and prevent it from being bent due to excessive force. During operation, the vibration motor 7 is started. Under the action of the vibration motor 7, the vibration of the vibration motor 7 drives the screening plate 2 to vibrate. The screening plate 2 moves up and down on the guide rod 8 to achieve the vibration of the screening plate 2. After the screening plate 2 vibrates, the plastic particles on the screening plate 2 will be driven to shake. The shaking of the plastic particles will cause the accumulated plastic particles to be dispersed by the vibration, and the accumulated plastic particles will be spread flat on the screening plate 2, thereby achieving the effect of separating and spreading the accumulated plastic particles by vibration, and solving the problem of poor screening effect caused by the accumulation of plastic particles on the screening plate 2.

[0026] Example 2

[0027] refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the upper surface of the screen plate 2 is further provided with a distribution component 12, the distribution component 12 is mainly used to distribute the plastic particles, the distribution component 12 includes three groups of material distribution components 13, the three groups of material distribution components 13 are respectively arranged in front of the screen plate 2 entering the screen hole, matching the position and number of the screen holes, not limited to three groups, so that the plastic particles ready to reach the screen hole are distributed, so that the plastic particles entering the screen hole are distributed first, which improves the screening effect, and a flexible connecting layer 24 is provided between the side of the screen plate 2 and the collection box 1 to fill the gap between the screen plate 2 and the collection box 1 to prevent plastic particles from getting stuck in this position, and the material distribution component 13 includes a fixing seat 14, which is fixed to the screen plate 2, a cross bar 15 parallel to the screen plate 2 is provided on the fixed seat 14 at a position away from the screen plate 2, and the number of fixed seats 14 corresponding to each set of material-diverting components 13 is two groups, and the two groups of fixed seats 14 are respectively arranged at both ends of the cross bar 15 and staggered in the screening hole area to prevent the fixed seat 14 from blocking the plastic particles from rolling on the screening hole. A dial tube 16 is movably sleeved on the surface of the cross bar 15. It should be noted that the cross bar 15 is a quadrangular prism rod, and the shape of the inner wall of the dial tube 16 matches the surface shape of the quadrangular prism rod. A dial rod 17 is provided on the surface of the dial tube 16 near the screen plate 2. The number of the dial rod 17 is multiple groups, and multiple groups of dial rods 17 are equidistantly arranged on the dial tube 16, so that when the dial tube 16 is active, the dial rod 17 will be driven to slide to divert the plastic particles. The lower surface of the dial rod 17 extends to the upper surface of the screen plate 2. An integral rod 18 is fixedly connected between the three groups of dial tubes 16. A reciprocating drive frame 19 is provided on the connecting rod on the dial tube 16 near the middle position of the three groups of dial tubes 16. The reciprocating drive frame 19 is provided with a shifting tooth 20, and a turntable 21 is provided on the shifting tooth 20. The turntable 21 is located above the reciprocating drive frame 19. A drive motor 22 is provided on the top of the turntable 21. The drive motor 22 is an existing reduction motor and is not described here. A mounting plate 23 is provided on the drive motor 22. The mounting plate 23 is fixedly connected to the upper surface of the screen plate 2 near the outermost position. The mounting plate 23 mounts the drive motor 22 on the screen plate 2. It should be noted that the entire dialing assembly 12 follows this screening. The plate 2 moves up and down. During operation, the drive motor 22 is started, and the drive motor 22 starts to drive the turntable 21 to rotate. The rotation of the turntable 21 drives the shifting gear 20 to rotate. The rotation of the shifting gear 20 drives the reciprocating drive frame 19 to reciprocate. The reciprocating drive frame 19 drives the shifting tube 16 to reciprocate along the cross bar 15 on the cross bar 15. The reciprocating movement of the shifting tube 16 drives the shifting rod 17 to reciprocate on the screening plate 2. The reciprocating movement of the shifting rod 17 performs a shifting operation on the plastic particles on the screening plate 2, thereby further dispersing the accumulated plastic particles and achieving flattening. Then the shifting rod 17 will also block the movement speed of the plastic particles, so that the plastic particles slide up and down the screening plate 2 at a slower speed, and have enough time to be screened by the screening plate 2, thereby greatly improving the screening effect.Avoid the accumulation of plastic particles and the rapid movement speed that may affect the screening effect.
