Description

Technical Field

[0002] In the fields of plastic processing, material recycling and related industries, plastic particles, as the basic conveying objects, often need to be orderly transferred, conveyed and quantitatively controlled before entering the next process; at present, common particle conveying methods include screw conveying, belt conveying and vibrating conveying, etc.; among them, vibrating conveying is widely used in the short-distance conveying and directional control of particulate materials due to its simple structure, convenient maintenance and strong adaptability to particle morphology.

[0003] Existing vibrating conveying devices are mostly driven by electromagnetic or eccentric motors to generate periodic vibrations on the bearing surface, thereby driving the materials to move in a specific direction; however, there are still several technical bottlenecks in specific applications: one is that the vibration path is fixed, and it is difficult to flexibly adjust according to different particle flow rates, particle sizes or on-site space requirements; the other is that the discharge structure is single, and particles are easy to accumulate or shift at the discharge port, affecting the conveying continuity; the third is that the adjustment of vibration intensity and frequency is not fine enough, which is easy to cause particle jumping, accumulation or unstable conveying, and then affect the overall conveying efficiency.

[0004] In view of the above, we provide a vibrating conveying device for plastic particles to solve the above problems, a plastic particle intelligent conveying device with features such as multi-point discharging, controllable direction and flexible adaptation, so as to improve the stability and continuity of particles during conveying and meet the requirements of modern production lines for efficient and adjustable conveying solutions.

Detailed implementation mode

[0071] Regarding the foregoing and other technical contents, features and effects of the present invention, they can be clearly presented in the following detailed description of the embodiments in conjunction with the attached Figures 1 to 12 drawings. The structural contents mentioned in the following embodiments are all referenced to the drawings of the specification.

[0072] Reference can be made to Figure 1 This application mainly consists of a storage rack 1, a turnover box 2 provided on the storage rack 1 for plastic particles to enter, two discharge ports 3 provided at the bottom of the turnover box 2, two hoppers 4 corresponding to the two discharge ports 3, a discharge assembly 5 for controlling the flow output of plastic particles, a vibrating feeding assembly 6 for vibrating and forwardly conveying plastic particles, a sorting assembly 7 provided at one end of the vibrating feeding assembly 6 away from the discharge assembly 5, a roller 8 provided below the sorting assembly 7, an adjusting assembly 9 for adjusting and driving the roller 8, and a conveying assembly 10 for receiving the plastic particles falling from the roller 8. Through the settings among the components, they are promoted to cooperate with each other. This device has significant advantages in improving sorting efficiency, optimizing the flow of plastic particles, preventing blockage, and realizing intelligent conveying through the combined mechanism of "multi-point discharging + flow control vibration + automatic sorting + roller conveying + flexible adjustment", and is especially suitable for scenarios with high-precision and high-efficiency processing requirements for fiber-like granular plastic particles, such as industries like textile, environmental protection, and new material production.

[0073] Reference can be made to Figures 1-2, the storage rack 1 is used for support, and its height is not limited. It can be adapted to the height requirements of the production line. The storage rack 1 includes a frame 1001, a connecting rod 1002, a mounting plate 1003, and a support shaft 1004. The connecting rod 1002 is arranged in the middle of the upper surface of the frame 1001. The mounting plate 1003 is detachably arranged on the connecting rod 1002. The support shafts 1004 are distributed annularly along the mounting plate 1003 and are installed on the frame 1001. The turnover box 2 is arranged through the middle of the mounting plate 1003. When feeding, the plastic particles are poured inward from the turnover box 2. After pouring plastic particles for a long time, there will be accumulations such as plastic particle powder in the turnover box 2. To avoid this situation, the mounting plate 1003 is set to be detachable. By disassembling the mounting plate 1003, the turnover box 2 arranged on the mounting plate 1003 is synchronously disassembled. At this time, further cleaning work can be done on the turnover box 2.

[0074] For reference Figures 1-5 , two discharge ports 3 are arranged at the bottom of the turnover box 2, and two hoppers 4 are correspondingly arranged for discharging work. This setting can avoid the situation that the turnover box 2 is too large and the flow rate is too large when directly conveying plastic particles to the two hoppers 4, which is not easy to control. At the same time, it can also reduce the feeding frequency, avoid the feeding frequency into the turnover box 2 being too large, and prevent the occurrence of fault conveying when feeding the turnover box 2. By reducing the design size of the turnover box 2 and adopting the setting of output through two discharge ports 3, it makes the whole more conducive to subsequent conveying control and avoids the intermittent output of plastic particles.

[0075] For reference Figures 3-5 , there are two groups of hoppers 4, which are correspondingly arranged for the two discharge ports 3 to receive and divert the falling plastic particles. In order to avoid the plastic particles being orderly and adjustable in flow rate when discharging again and control the output of the plastic particles, an outlet assembly 5 is further arranged at the bottom of the hopper 4 to control the output frequency of the plastic particles from the hopper 4.

[0076] In view of the above, through the two discharge ports 3 and the two corresponding hoppers 4, the equipment can realize the shunt treatment of different plastic particles or the same plastic particles by batch and type, which is convenient for subsequent independent screening or packaging and improves the sorting efficiency of the production line.

[0077] For reference Figure 5, the discharge assembly 5 includes a support 51, a fixed plate 52, a discharge guide frame 53, a flow regulating unit 54, an adjusting unit 55 and a regulating valve 56; the support 51 is arranged at the bottom of the hopper 4, the fixed plate 52 is arranged on the support 51, the discharge guide frame 53 is installed on the upper surface of the fixed plate 52, the flow regulating unit 54 is slidably connected to the fixed plate 52 through a slideway, both side surfaces of the adjusting unit 55 are engaged with both sides of the flow regulating unit 54, and both ends of the adjusting unit 55 penetrate through the fixed plate 52 and are connected to the regulating valve 56;

[0078] Furthermore, the support 51 is used to support the discharge assembly 5, and secondly, it can also assist in the installation of the vibrating feeding assembly 6. When the connection between the bottom of the support 51 and the storage rack 1 is adjusted to the appropriate height by the support frame 11, the support 51 is set to the appropriate height for use accordingly; there are three fixed plates 52, and the three fixed plates 52 are respectively arranged corresponding to the two hoppers 4. The flow regulating unit 54, the adjusting unit 55 and the regulating valve 56 are further penetrated through the fixed plate 52. Through the movement of the regulating valve 56, the adjusting unit 55 is driven to rotate. When the adjusting unit 55 rotates, the flow regulating unit 54 is further driven to move, so as to change the connection gap between the flow regulating unit 54 and the discharge guide frame 53, thereby realizing the control of the discharge flow rate.

[0079] Furthermore, as Figure 5 shown, the discharge guide frame 53 is arranged in an L shape and is used to receive the plastic particles falling from the hopper 4. A vibration motor 531 is arranged on its outer surface and is used to provide micro-vibration during the discharging process to prevent particle retention or blockage.

[0080] Specifically:

[0081] The adjusting unit 55 includes a round rod 551 and a toothed shaft 552. Both sides of the round rod 551 penetrate through the fixed plate 52. There are four toothed shafts 552, which are fixedly installed on the toothed shaft 552. The round rod 551 is manually driven by the regulating valve 56 to rotate, thereby driving the toothed shaft 552 to rotate left.

[0082] There are two sets of flow regulating units 54, which correspond to the two hoppers 4 and work inside the discharge guiding frame 53. The flow regulating unit 54 includes a shielding plate 541, a tooth block 542 and a speed regulating plate 543. One side of the tooth block 542 is connected through a slideway fixing plate 52. There are two tooth blocks 542 located on both sides of the shielding plate 541 and engaged with the tooth shaft 552 for movement. The shielding plate 541 forms the main shielding work. And in the two sets of flow regulating units 54, there are two sets of shielding plates 541, and correspondingly, four tooth blocks 542 are provided. The four tooth blocks 542 are engaged with the four tooth shafts 552 and are all driven by a regulating valve 56 to rotate the tooth shafts 552, driving the tooth blocks 542 to move up and down along the slideway. The speed regulating plate 543 is detachably installed on the shielding plate 541. Since the bottom of the speed regulating plate 543 will have a direct frictional relationship with the plastic particles during output, a plastic protective layer is provided on the surface of the speed regulating plate 543 to avoid its influence on the plastic particles. At the same time, the speed regulating plate 543 is designed to be detachable, so that it can be replaced when the speed regulating plate 543 is worn out.

[0083] In view of the above, the discharge assembly 5 is equipped, which can accurately control the output speed of plastic particles at each discharge port according to the required production capacity, avoiding blockage, waste or efficiency reduction caused by too fast or too slow discharge.

[0084] For reference Figures 3-4 , the vibrating blanking assembly 6, one end of which is arranged at the output end of the discharge assembly 5. The vibrating blanking assembly 6 includes a bearing plate 61 and a vibrating unit 62. The bearing plate 61 is detachably arranged at the output end of the discharge assembly 5. Its whole is composed of a plurality of V-shaped grooves combined into a wave shape. The vibrating unit 62 is arranged on the lower surface of the bearing plate 61. The plastic particles input from the discharge assembly 5 onto the bearing plate 61 are vibrated forward by the vibrating unit 62 and enter the sorting assembly 7. During the conveying process, the shape of the bearing plate 61 divides the plastic particles and distributes them evenly in a plurality of V-shaped grooves for forward conveying work.

[0085] In view of the above, the plastic particles are conveyed forward by the vibrating blanking assembly 6, which can not only prevent the plastic particles from staying due to static electricity or adhesion, but also make the plastic particles more evenly distributed, facilitating subsequent processing.

[0086] For reference Figures 6-12, is arranged at one end of the vibrating feeding assembly 6 away from the discharging assembly 5; wherein, one end of the sorting assembly 7 away from the vibrating feeding assembly 6 is arranged to incline downward, and the optimal inclination angle is 20% downward. The sorting assembly 7 includes an upper frame 71 and a lower frame 72. One end of the upper frame 71 is rotatably connected to the lower frame 72. A plurality of U-shaped grooves 73 are arranged on the surface of the lower frame 72. The plurality of U-shaped grooves 73 are arranged corresponding to the V-shaped grooves on the bearing plate 61. A notch 74 for discharging materials is opened at the bottom of the plurality of U-shaped grooves 73. Plastic particles enter the lower frame 72, and the plastic particles conveyed from the vibrating feeding assembly 6 are respectively received by the U-shaped grooves 73. After the plastic particles are conveyed to the sorting assembly 7 by the vibrating feeding assembly 6, they enter the U-shaped grooves 73. Particles smaller than the notch 74 fall between the inclined rollers 8, and further grading and screening are realized according to the spacing of the rollers 8. Thus, by controlling the falling frequency in the previous process and adopting the method of vibrating forward, it is promoted to move forward without rushing forward, but gently enter the U-shaped grooves 73, and then fall downward through the notch 74 into the rollers 8; a large number of situations of mutual accumulation will be avoided during the whole process of the previous control.

[0087] It should be noted that both the vibration motor 531 and the vibrating unit 62 are common small vibrating devices in the prior art (the model is not limited, and the appropriate model is selected according to different use positions). When the device operates, the vibration frequency can be adjusted according to the use situation, so as to realize different vibration intensities and discharging rhythms, realize the precise control of the material output volume, and improve the production automation level. The vibrating unit 62 is a common technology in the prior art, and the specific implementation manner is not described in detail in this application.

[0088] After entering the U-shaped groove 73, the plastic particles with a diameter smaller than the groove opening 74 fall through the groove opening 74 onto the roller 8. The roller 8 is inclined. Two rollers 8 are provided directly below each groove opening 74. Through the adjustment of the adjustment component 9, the distance between a pair of symmetrically arranged rollers 8 is adjusted to make a small-range diameter adjustment (range: 5 - 10 mm) to adapt to the diameter of the plastic particles. When the roller 8 was originally arranged on the lower frame 72, it was also inclined. The two inclined rollers 8 are symmetrically arranged, so that the distances at their front and rear ends are different, thus being divided into two sections. In one embodiment, the diameters of the two divided sections are the required diameters of 3 - 5 mm and 5 - 10 mm. The section of 3 - 5 mm is arranged closer to the vibrating feeding component 6. When the plastic particles enter the sorting component 7, the first screening of the plastic particles is carried out, and the over-sized plastic particles are first screened out. The plastic particles that meet the specifications and are smaller than or equal to the size of the required plastic particles fall downward. When falling, they will directly fall from the corresponding groove opening 74 into the space above the roller 8 arranged at the distance of 3 - 5 mm for processing. If the distance between the falling plastic particles matches the distance of 3 - 5 mm, the plastic particles will fall from the 3 - 5 mm section of the roller 8 into the conveying component 10 for further processing. If the diameter is greater than 3 - 5 mm, the plastic particles will slide to the two groups of rollers 8 in the distance of 5 - 10 mm and fall from this distance into the conveying component 10 for processing. It should be noted that the maximum diameter of the roller 8 is larger than the size of the groove opening 74.

[0089] In view of the above, the sorting component 7 is arranged at the end of the feeding, and can classify according to the material size, density or other physical properties, improving the automation degree and reducing the manual burden.

[0090] It should be noted that the adjustment of the roller 8 is realized through the adjustment component 9. The adjustment component 9 is arranged on both sides of the roller 8 and is used to adjust the distance between the driving rollers 8. The adjustment component 9 includes a square shaft 91, a first positioning rod 92, a second positioning rod 93, a driving valve 94 and a conveyor belt unit 95. There are multiple square shafts 91, which are arranged on the lower frame 72. The top of the surface of the square shaft 91 is rotationally connected to the roller 8. There are two first positioning rods 92, which are symmetrically arranged. The two first positioning rods 92 penetrate through the middle parts of the surfaces of multiple square shafts 91 on both sides. One end of each of the two first positioning rods 92 is connected to a driving valve 94. There are two second positioning rods 93, which are symmetrically arranged. The two first positioning rods 92 penetrate through the bottom parts of the surfaces of multiple square shafts 91 on both sides. The conveyor belt unit 95 drives the two symmetrically arranged rollers 8 to rotate in opposite directions.

[0091] One of the first positioning rods 92 is fixedly connected to the square shaft 91 connected to one of the two groups of symmetrically arranged rollers 8. The other first positioning rod 92 is fixedly connected to the square shaft 91 connected to the other of the two groups of symmetrically arranged rollers 8.

[0092] Further, two first positioning rods 92 are replaced by rod A and rod B for illustration; rod A and rod B are symmetrically arranged on both sides of the roller 8. A square shaft 91 is connected to both ends of one roller 8, and the left and right positions of the roller 8 are used for illustration; that is, a square shaft 91 is provided on both the left and right sides of the roller 8. The square shafts 91 connected to the left sides of all the rollers 8 are penetrated by rod A, and the square shafts 91 connected to the right sides of all the corresponding rollers 8 are penetrated by rod B; at the same time, the rollers 8 are arranged in two groups symmetrically; for one of the two symmetrically arranged rollers 8, the square shaft 91 on the left side is fixedly connected to rod A, then the square shaft on the right side is sleeved on rod B (can slide along the surface of rod B). For the other roller 8 in the above two symmetrically arranged groups, the square shaft 91 on the left side is sleeved on rod A (can slide along the surface of rod A), and the square shaft 91 on the right side is fixedly connected to rod B. Each group of rollers 8 (and the two symmetrically arranged rollers 8) are arranged in the same orientation. For example, the two groups are arranged one above the other. The square shafts 91 arranged on the upper side are all fixedly connected to rod A, and the lower side is fixedly connected to rod B.

[0093] In view of the above, the rollers 8 arranged below the sorting assembly 7 can further perform rolling classification and conveying on the sorted particles, reduce material accumulation, prevent material blockage, and are equipped with an adjustment assembly 9 to flexibly adjust the rolling state.

[0094] Set in sequence, when the drive valve 94 on rod A moves during adjustment, it drives all the square shafts 91 fixedly connected to rod A to move, and the moving range of each group after adjustment is also the same. Only the width of one group needs to be adjusted accordingly; according to the movement of the square shafts 91 fixedly connected to rod B above, the movement is also carried out through the drive valve 94 connected to rod B, so as to complete the adjustment of the spacing; thus, the situation of uneven intervals after sleeving can be reduced.

[0095] In view of the above, the conveying assembly 10 receives the plastic particles falling from the rollers, plays a role of transitional conveying, and can be seamlessly connected with packaging, weighing or the next production link to form a complete and continuous flexible production line layout.

[0096] Can participate Figure 1 On the support, a support frame 11 is provided. Due to the need to meet the requirement that the sorting assembly 7 and the rollers 8 are inclined, the support frame 11 is further arranged. The conveying assembly 10 includes a guide plate 101, a shielding frame 102, a conveyor belt 103 and a conveying hopper 104;

[0097] The guide plate 101 is arranged on the inner surface of the lower frame 72. There are two guide plates 101 in a set of conveying components 10. Both of the two guide plates 101 are arranged obliquely towards the direction of the conveyor belt 103. The shielding frame 102 is arranged directly below the guide plate 101. The conveyor belt 103 is arranged on the shielding frame 102. The conveying hopper 104 is arranged on one side of the shielding frame 102 and is used to receive the plastic particles output from one side of the output end of the conveyor belt 103.

[0098] The support frame 11 includes a guardrail 111, an extension unit 112 and a bottom support 113. The guardrail 111 is installed and connected to the bottom of the lower frame 72, widening the distance between the lower frame 72 and the extension unit 112, which is convenient for reducing the collision between the adjustment component 9 and the conveying component 10 arranged at the bottom of the lower frame 72 and the extension unit 112 during subsequent movement. The top of the extension unit 112 is rotatably connected to the bottom of the guardrail 111. The extension unit is used to adjust the specific height of the lower frame 72 and the auxiliary work of inclined setting. The top of the bottom support 113 is detachably connected to the bottom of the extension unit 112. The detachable setting enables the extension unit 112 to be convenient for disassembly, replacement and various adjustment works under different applications.

[0099] Specifically, the extension unit 112 includes a square beam 1121, a short beam 1122, a tall beam 1123, an inclined beam 1124 and an extension shaft 1125; the square beam 1121 is detachably connected to the bottom support 113; there are two short beams 1122, which are symmetrically arranged on the square beam 1121. There are two tall beams 1123, which are symmetrically arranged with the two short beams 1122. One end of the inclined beam 1124 is connected to the short beam 1122, and the other end is connected to the top of the surface of the tall beam 1123. The extension shaft 1125 is detachably connected to the short beam 1122;

[0100] The square beam 1121 realizes the disassembly and connection relationship with the bottom support 113. The short beam 1122 and the tall beam 1123 cooperate to make the structure supported at the top inclined. During this period, the extension shaft 1125 is used to control the height on the side of the short beam 1122 so that the required inclination angle is achieved after adjustment. At the same time, the inclined setting of the inclined beam 1124 promotes the stability of its connection and can also increase the protection when the two sides collide with the internal structure.

[0101] It should be noted that during installation, both the bottom support 113 and the tall beam 1123 are connected to the storage rack 1 through installation to promote the connection stability of the overall equipment.

[0102] Therefore, the entire equipment is composed of multiple functional unit modules, such as storage, vibration, sorting, transportation, adjustment, etc., which can be individually adjusted or combined and upgraded according to the actual production line needs. It has good flexibility and adaptability, and supports flexible upgrades and production line integration. The open structure of the device is conducive to disassembly and reorganization, and can be used in conjunction with existing conveying systems, weighing devices or sorting equipment to achieve flexible module expansion, reduce production line transformation costs, and improve the level of automation.

[0103] In view of the above, the specific operation steps of the device are as follows:

[0104] 1. First, the plastic particles to be processed are placed into a plurality of turnover frames 2 according to different sizes or types. The turnover frames 2 can be arranged in order along the storage rack 1 to facilitate subsequent unloading and identification.

[0105] 2. Then, the discharge assembly 5 is controlled to start, so that the discharge port 3 at the bottom of the hopper 4 is opened, and the plastic particles fall into the vibrating discharge assembly 6 in sequence by gravity.

[0106] 3. Then, the vibration unloading component 6 starts to work, generating regular vibrations to loosen the plastic particles and arrange them in sequence, preventing blockage or accumulation, and providing a good feeding state for subsequent transportation.

[0107] 4. Subsequently, the plastic particles enter the sorting component 7 for size screening. The sorting component 7 is provided with a plurality of sorting channels or adjustable openings, which can distinguish the plastic particles according to their sizes and guide the qualified plastic particles into the next process.

[0108] 5. The screened plastic particles fall onto the roller 8 and are transported stably and orderly by the roller 8. The roller speed and spacing are set by the adjustment component 9 to ensure that the plastic particles do not slip or get stuck.

[0109] 6. If you need to adapt to plastic particles of different specifications, you can operate the adjustment component 9 to adjust the sorting opening size, roller spacing or vibration parameters to achieve rapid response and flexible upgrade of the system.

[0110] 7. Finally, the plastic particles conveyed by the roller 8 are delivered to the conveying component 10, which completes the final directional output or docks to the downstream station, and the entire process realizes automatic sorting and conveying control.

[0111] The above is only for illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
