In the process of producing plastic products, plastic particles need to be transported to the feed inlet of production and processing equipment. In the past, plastic particles were transported manually. With the advancement of technology, an intelligent plastic particle conveying device has appeared on the market. It uses equipment to drive plastic particles for automatic transportation, reducing the burden on staff. During production and processing, unqualified plastic particle diameters will cause large differences in the fluidity of the plastic during injection molding, and the dimensional accuracy of the molded product will not be high, which is prone to deformation, warping and other problems. This not only increases the difficulty of subsequent processing, but may also lead to an increase in product scrap rate, thereby reducing production efficiency.

[0003] In the process of conveying plastic particles, plastic particles of different sizes are mixed. The diameter of some plastic particles is larger than the standard diameter required for production, and the diameter of some plastic particles is smaller than the standard diameter required for production.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1 like Figure 1 and Figure 2As shown, a plastic particle anti-blocking conveying device includes a conveyor 1 and a motor 8. The conveyor 1 is a prior art and is used to convey the processed plastic particles to the production device. An installation box 2 is fixed on the upper end of the conveyor 1. A collection box 3 is fixed on the end of the installation box 2 away from the conveying direction of the conveyor 1. Figure 1 As shown, the conveying direction in the conveyor 1 is clockwise, and a feeding component 4 is fixed on the upper end of the installation box 2. The feeding component 4 is used to break up the agglomerated plastic particles to prevent the feeding component 4 from being blocked; Then, if Figure 2 In the embodiment, two parallel filter components 5 are provided on the side wall of the inner cavity of the installation box 2 close to the collecting box 3, and the filter components 5 are fixedly connected to the inner cavity side wall of the installation box 2. A material discharge assembly 9 matching the two filter components 5 slides in the inner cavity of the installation box 2, and a particle processing component 7 is provided on the side wall of the inner cavity of the installation box 2 away from the collecting box 3, and the particle processing component 7 is fixedly connected to the inner cavity side wall of the installation box 2. A triangular stopper 6 is fixed on the upper end of the particle processing component 7, and the inclination angle of the triangular stopper 6 away from the side wall of the installation box 2 is located in the middle of the filter component 5, so as to facilitate receiving the plastic particles sliding down from the upper surface of the triangular stopper 6, and a motor 8 is used to drive the particle processing component 7; Among them, an inclined plate cooperating with the collecting box 3 is provided on the lower side of the filtering component 5, and the inclined plate is obliquely fixed to the side wall of the inner cavity of the installing box 2. A through groove communicating with the inner cavity of the collecting box 3 is opened on the side wall of the installing box 2 above the connection between the inclined plate and the side wall of the installing box 2, which is used to collect unqualified plastic particles screened by the filtering component 5.

[0022] Further, if Figure 3 and Figure 4 As shown, the filter component 5 includes a filter plate 50, which is fixedly installed in the inner cavity of the installation box 2 at an angle, but will not affect the filter plate 50 to screen the plastic particles under the action of the vibration motor 55. The upper end of the filter plate 50 is provided with a plurality of filter holes 56, and the diameter of the filter hole 56 is 2 mm. The upper surface of the filter plate 50 is slidably connected to two symmetrically arranged straight plates 51, and a plurality of limit plates 52 are fixedly connected between the two straight plates 51; Next, multiple limiting plates 52 are matched with multiple groups of filter holes 56. The upper end of the limiting plate 52 is provided with a semicircular hole aligned with the filter hole 56. By adjusting the position of the limiting plate 52, the diameter of the plastic particles that can be filtered by the filter hole 56 can be changed. The thickness of the straight plate 51 will not affect the sieving of plastic particles by the filter plate 50. The end of the two straight plates 51 close to each other and away from the particle processing component 7 are commonly fixed with a positioning plate 53. The positioning plate 53 is tightly attached to the upper surface of the filter plate 50. The end of the positioning plate 53 away from the installation box 2 is threadedly connected with a screw rod 54. The screw rod 54 is rotatably connected to the installation box 2. Rotating the screw rod 54 can make the positioning plate 53 slide on the upper surface of the filter plate 50, thereby moving the multiple limiting plates 52 between the two straight plates 51. The semicircular hole at the upper end of the limiting plate 52 moves toward the filter hole 56 on the filter plate 50, reducing the inlet diameter of the filter hole 56, so that the diameter of the plastic particles that can be filtered by the filter hole 56 becomes smaller, thereby adjusting the diameter of the plastic particles filtered by the device; Next, an adjustment ruler matched with the positioning plate 53 is embedded on the upper end of the filter plate 50. The adjustment ruler is located at the lower side of the positioning plate 53. During the movement of the positioning plate 53, the position of the positioning plate 53 pointing to the adjustment ruler will also change. The distance moved by the positioning plate 53 is the same as the distance moved by the plurality of limit plates 52. The distance moved by the positioning plate 53 is the same as the value of the reduction in the diameter of the filter hole 56 at the upper end of the filter plate 50. That is, the initial diameter of the filter hole 56 minus the distance moved by the positioning plate 53 is the diameter of the plastic particles that can be filtered after the positioning plate 53 changes its position. In addition, a vibration motor 55 is fixed to the side of the lower end of the filter plate 50 away from the particle processing component 7, and the vibration motor 55 helps the filter plate 50 to perform screening.

[0023] Further, if Figure 5 and Figure 6 As shown, the blanking assembly 9 includes an electric cylinder 90 fixed to one end of the installation box 2, and the output end of the electric cylinder 90 is fixed with an output block 91 located in the inner cavity of the installation box 2 through a connecting block. The output block 91 slides up and down on the side wall of the inner cavity of the installation box 2 along with the output end of the electric cylinder 90, and the sliding distance is set, and is used to cooperate with the two filter components 5. The filter components 5 are slidably connected with the output block 91; Next, an inclined groove 92 is provided on the upper side of one end of the output block 91 close to the filter component 5. The inclined groove 92 penetrates the output block 91, and the inclined angle of the inclined groove 92 is the same as the inclined angle of the filter component 5, so that the filter plate 50 and the bottom wall of the inner cavity of the inclined groove 92 can be in the same straight line. A material blocking plate is fixed at the lower end of the triangular stopper 6 to prevent plastic particles from entering the inner cavity of the inclined groove 92 when screening coarse particles. The output block 91 has a discharge port 95 at its lower end, and the discharge port 95 is used to discharge the plastic particles that meet the standards that are screened out. The output block 91 has a first discharge port 93 and a second discharge port 94 that are connected to the discharge port 95 at one end close to the filter component 5. The second discharge port 94 is located at the lower side of the first discharge port 93. Among them, the chute 92, the first feeding port 93, and the second feeding port 94 cooperate with the two filtering components 5. When it is necessary to screen the coarse plastic particles, such as Fig.10 As shown, the baffle plate at the lower end of the triangular block 6 blocks the chute 92, and the discharge port 1 93 corresponds to the upper filter component 5. The screening diameter of the upper filter component 5 is not adjusted, so that the diameter of the screened plastic particles is greater than 2 mm, and the screened plastic particles flow from the discharge port 1 93 to the inner cavity of the discharge port 95 and then are transported; When you need to screen medium-sized plastic particles, such as Fig.11As shown, the output block 91 is moved downward by the electric cylinder 90. At this time, the chute 92 corresponds to the upper filter component 5, and the second discharge port 94 corresponds to the lower filter component 5. The upper filter component 5 screens plastic particles with a diameter greater than 2 mm. The lower filter component 5 is adjusted to make the screening diameter greater than 0.3 mm. In this way, plastic particles with a diameter greater than 2 mm are transported from the upper filter component 5 to the inner cavity of the particle processing component 7 through the chute 92 for processing, and plastic particles that meet the medium particle standard are transported from the lower filter component 5 to the inner cavity of the second discharge port 94 and discharged through the discharge port 95. When you need to screen fine plastic particles, such as Fig.11 As shown, the chute 92 corresponds to the upper filter component 5, and the second discharge port 94 corresponds to the lower filter component 5. The upper filter component 5 is adjusted to allow the upper filter component 5 to screen plastic particles with a diameter greater than 0.3 mm, and then transport them from the chute 92 to the particle processing component 7 for processing. The lower filter component 5 is adjusted to allow the lower filter component 5 to screen plastic particles with a diameter greater than 0.1 mm. Plastic particles that meet the fine particle standard are discharged through the second discharge port 94 and the discharge port 95.

[0024] It should be noted that the standard diameter of plastic particles during production is usually a range of values, which mainly depends on the specific purpose of the particles, the production process and the performance standards to be achieved. Coarse particles (>2.0 mm): generally used for injection molding, extrusion and other processes, which require larger particles to ensure the fluidity and filling properties of the plastic; medium particles (0.3 mm - 2.0 mm): commonly used in processes such as blow molding, medium-sized particles can provide good melt fluidity and uniform wall thickness during blow molding; fine particles (0.1 mm - 0.3 mm): suitable for spraying, pressure injection molding and other processes, fine particles can provide better surface quality and finer molding details.

[0025] Further, if Figure 7 - Fig. 9 As shown, the particle processing component 7 includes a triangular block 70, the inclined surface of the triangular block 70 is on the same horizontal line as the bottom wall of the inner cavity of the chute 92, so that the plastic particles with a diameter larger than the standard screened by the upper filter component 5 roll through the inner cavity of the chute 92 toward the inclined surface of the triangular block 70, and a crushing box 71 is fixed on the side of the horizontal lower end of the triangular block 70 away from the filter component 5, and a crushing roller 73 is rotatably connected to the inner cavity of the crushing box 71. The crushing box 71 and the crushing roller 73 cooperate to crush the plastic particles again, so that the diameter of the screened plastic particles becomes smaller, and the crushing box 71 and the upper end of the triangular block 70 are fixed with a matching block 72; Among them, Figure 8As shown, a feeding trough 7201 parallel to the inclined surface of the triangular block 70 is provided on one side of the lower end of the matching block 72 close to the triangular block 70. The cross section of the feeding trough 7201 is a parallelogram, which is used to transport the plastic particles on the inclined surface of the triangular block 70 to the inner cavity of the crushing box 71. A cylindrical groove is provided on the upper side wall of the feeding trough 7201 and the inclined surface of the triangular block 70. A material shifting rack 7202 is rotatably mounted on the side wall of the inner cavity of the cylindrical groove. A rectangular groove 7203 adapted to the inner cavity of the crushing box 71 is provided on one side of the lower end of the matching block 72 close to the crushing box 71. In addition, if Figure 8 As shown, the material rack 7202 includes a mounting shaft and four matching plates. The mounting shaft passes through the mounting box 2 and extends out of the inner cavity of the mounting box 2. The matching plates are in close contact with the side walls of the cylindrical grooves, and the plastic particles passing through the inclined surface of the triangular block 70 can be transported to the inner cavity of the crushing box 71 at intervals to prevent the plastic particles from being blocked in the inner cavity of the feeding chute 7201. Further, if Fig. 9 As shown, a transfer barrel 74 communicating with the inner cavity of the crushing box 71 is fixed at the lower end of the crushing box 71, and a conveying auger 75 is rotatably connected to the inner cavity of the transfer barrel 74. The conveying auger 75 is used for feeding. A top barrel 76 is provided on one side of the discharge port of the transfer barrel 74. The conveying auger 75 in the inner cavity of the transfer barrel 74 conveys the crushed plastic particles to the inner cavity of the upper barrel 76. The place where the transfer barrel 74 and the upper barrel 76 communicate is the discharge port of the transfer barrel 74. The inner cavity of the upper barrel 76 is rotatably connected to a conveying auger 2 77. The diameter of the lower side of the inner cavity of the upper barrel 76 is larger than the diameter of the conveying auger 2 77 installed on the upper side, so as to facilitate the storage of the crushed plastic particles and then convey them. Next, a discharge pipe 78 communicating with the inner cavity of the installation box 2 is provided on the outer surface of the second conveying auger 77. The discharge pipe 78 is fixed on the outer surface of the second conveying auger 77 and communicates with the inner cavity of the second conveying auger 77. The discharge pipe 78 is used to deliver the plastic particles transported by the second conveying auger 77 to the inclined surface of the triangular stopper 6 in the inner cavity of the installation box 2 again, and then slide along the inclined surface of the triangular stopper 6 to fall on the upper surface of the upper filter component 5 for re-screening, thereby reducing the unqualified rate of plastic particles and improving the production efficiency of the device; Among them, the motor 8 drives the conveying auger 2 77 to rotate through a group of bevel gears. The motor 8 is fixed at the end of the installation box 2 away from the loading barrel 76. A group of bevel gears are installed at the output end of the motor 8, which is fixedly connected to the output end of the motor 8 in the vertical direction and fixedly connected to the conveying auger 2 77 in the horizontal direction, and can drive the conveying auger 2 77 to rotate. The material shifting rack 7202, the crushing roller 73 and the conveying auger 1 75 are connected by a belt. The output end of the motor 8 is connected to any one of the material shifting rack 7202, the crushing roller 73 and the conveying auger 1 75 through a belt. The motor 8 is used to make the material shifting rack 7202, the crushing roller 73, the conveying auger 1 75 and the conveying auger 2 77 rotate at the same time.

[0029] It should be noted that the conveyor 1, the vibration motor 55, the crushing roller 73 and the conveying auger in the present invention are all prior arts, and their installation methods and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0030] Specific implementation of the device: The device is a plastic particle anti-blocking conveying device, which can break up the plastic particles with larger diameters that have been screened out, and then screen them again, which can reduce the waste of plastic particles and improve production efficiency; Specifically, Fig.12 and Fig.13As shown, when the device is in use, the plastic particles are transported to the trapezoidal feed slot at the upper end of the feed block 40, and the motor 2 4305 drives the bevel gear 2 4306 to rotate, so that the two bevel gears 1 4303 drive the transmission tube 4302 and the transmission rod 4301 to rotate respectively. The transmission rod 4301 and the transmission tube 4302 rotate in opposite directions, so the two feed racks 42 rotate in opposite directions in the inner cavity of the cylindrical groove 1 41, so that the plastic particles in the inner cavity of the trapezoidal feed slot at the upper end of the feed block 40 fall into the inner cavity of the through groove 46 from two directions under the action of the two feed racks 42, and then fall from the inner cavity of the through groove 46 onto the two inclined surfaces of the diversion block 44, so as to realize the diversion of the plastic particles and avoid the plastic particles from being blocked in the inner cavity of the trapezoidal feed slot at the upper end of the feed block 40; Then, if Fig.15 As shown, during the rotation of the transmission rod 4301, the cam assembly 4503 can be driven by the belt to rotate the cam in the cam assembly 4503. The rotation of the cam in the cam assembly 4503 can push the adjacent limiting assemblies 4502 to move, so that the two extrusion blocks 4501 connected to the two limiting assemblies 4502 move toward the diverter block 44, which can squeeze the plastic particles on the inclined surface of the diverter block 44, thereby dispersing the agglomerated plastic particles on the inclined surface of the diverter block 44, and preventing the agglomerated plastic particles from clogging the filter plate 50, thereby affecting the screening efficiency of the device; Further, if Fig.10 As shown, the plastic particles processed by the feeding component 4 fall into the upper end of the filter plate 50 in the inner cavity of the installation box 2, and the filter plate 50 is vibrated by the vibration motor 55, so that the filter plate 50 screens the plastic particles on the upper end; When screening coarse plastic particles, Fig.10 As shown, the feed port 1 93 corresponds to the upper filter component 5, and the screening diameter of the upper filter component 5 is not adjusted, so that the diameter of the screened plastic particles is greater than 2 mm, and the screened plastic particles flow from the feed port 1 93 to the inner cavity of the discharge port 95 and then are transported; When screening medium-sized plastic particles, Fig.11 As shown, the output block 91 is moved downward by the electric cylinder 90, at which time the chute 92 corresponds to the upper filter component 5, and the second feed port 94 corresponds to the lower filter component 5. The lower filter component 5 is adjusted to make the screening diameter greater than 0.3 mm. In this way, plastic particles with a diameter greater than 2 mm are transported from the upper filter component 5 through the chute 92 to the inner cavity of the particle processing component 7 for processing; When screening fine plastic particles, Fig.11As shown, the chute 92 corresponds to the upper filter component 5, and the second discharge port 94 corresponds to the lower filter component 5. The diameters of the plastic particles filtered by the two filter components 5 are adjusted so that the upper filter component 5 screens the plastic particles with a diameter greater than 0.3 mm, and then transports them from the chute 92 to the particle processing component 7 for processing, so that the lower filter component 5 screens the plastic particles with a diameter greater than 0.1 mm, and the plastic particles that meet the fine particle standard are discharged through the second discharge port 94 and the discharge port 95; Then, the plastic particles with smaller diameters filtered out by the lower filter component 5 will slide down from the inclined plate into the inner cavity of the collection box 3, and those meeting the screening criteria will fall onto the conveyor 1 through the discharge port 95 and be transported to the production device; The method of adjusting the filtering diameter of the filtering component 5 is to rotate the screw 1 54 to make the positioning plate 53 and the two straight plates 51 slide on the upper end of the filtering plate 50, so that the semicircular hole on the upper end of the limiting plate 52 moves toward the filtering hole 56 on the upper end of the filtering plate 50, so that the diameter of the plastic particles that can be filtered by the filtering hole 56 becomes smaller, thereby adjusting the diameter of the plastic particles filtered by the device; Furthermore, the plastic particles filtered from the upper end of the filter plate 50 are transported to the cylindrical groove through the inclined surface of the triangular block 70 and the lower material groove 7201, and then the plastic particles are transported at intervals by the material transfer rack 7202 rotating in the inner cavity of the cylindrical groove, and then fall into the inner cavity of the crushing box 71. The intermittent transport of the plastic particles can avoid clogging of the crushing box 71. Next, the plastic particles entering the inner cavity of the crushing box 71 are crushed again by the crushing roller 73, and then fall into the inner cavity of the transfer barrel 74 and are transported to the inner cavity of the upper barrel 76 by the conveying auger 1 75, and then the conveying auger 2 77 transports the crushed plastic particles in the inner cavity of the upper barrel 76 upward, and transports them from the inner cavity of the discharge pipe 78 to the upper inclined surface of the triangular block 6, and then re-enters the upper end of the filter component 5 in the inner cavity of the installation box 2 for screening, which can reduce the loss of plastic particles and improve the production efficiency of the device.
