Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plastic particle production, and in particular to a plastic particle production device with product detection. Background Art
[0002] Plastic pellets are small particles made from plastic raw materials. They are widely used in industrial production. These pellets are usually produced through plastic processing and granulation processes and are used to make various plastic products.
[0003] The production of plastic pellets typically requires a plastic pellet production plant, which includes: A feeding system: Plastic raw materials are typically fed into the production line in the form of pellets, granules, or powder. The feeding system, which includes conveyor belts, bucket elevators, or vacuum conveying systems, is used to transport the raw materials from storage silos or bags to the production line.
[0004] Plasticizer (Extruder): A plasticizer heats, melts, and plasticizes plastic raw materials into a continuous, uniform melt. A plasticizer typically consists of a feeding section, a screw, heating / cooling areas, and an extruder. In the plasticizer, the plastic raw materials are heated above their melting point, and the screw rotates to extrude the melt.
[0005] Pelletizer: A granulator is used to cut continuously extruded plastic melt into solid pellets. It typically includes cutting tools, a cooling water tank, and a conveying system. After the melt is extruded from the extruder, it is cut into pellets of a predetermined length by the cutting tools. The pellets are then cooled and solidified in a cooling water tank before being collected and transported by the conveying system to subsequent processing equipment.
[0006] Cooling system: During the pelletizing process, the cooling system is used to quickly cool the melt and solidify it into pellets, and to control the pellet temperature to ensure product quality. Control system: The production line is usually equipped with an automated control system to monitor and control various parameters of the production process, such as temperature, pressure, speed, etc., to ensure that the produced plastic pellets meet the required specifications.
[0007] Usually after the production of plastic particles is completed, it is necessary to conduct random inspections on the plastic particles to detect whether the production of plastic particles is qualified. The main inspection items include plastic particle hardness, water content and other items. When measuring the hardness of plastic particles, the plastic particles will be placed on the hardness testing device for testing.
[0008] However, testing is often done after a batch of products has been produced. If unqualified products are discovered at this time, the losses caused are already very large, and there is a problem of not being able to test the products in a timely manner. Summary of the Invention
[0009] The purpose of this application is to provide a plastic particle production device with product detection, which can detect the hardness of the produced plastic particles at any time.
[0010] The present application provides a plastic particle production device with product detection, which adopts the following technical solutions:
[0011] A plastic particle production device with product detection, comprising:
[0012] Particle extruder, used to extrude raw materials into plastic particles;
[0013] a feeding mechanism connected to the particle extruder and used for feeding the particle extruder;
[0014] A collection box for collecting the finished plastic particles;
[0015] A discharge channel, one end of which is connected to the discharge port of the particle extruder and the other end of which is connected to the collection box, wherein the height of the discharge port of the particle extruder is higher than the height of the opening of the collection box;
[0016] A flow opening is provided on the side wall of the discharge channel, and a feeding assembly for discharging plastic particles from the flow opening is installed on the discharge channel;
[0017] a single-particle conveying mechanism, installed on the side of the discharge channel where the flow opening is located and used to convey one of the plurality of plastic particles;
[0018] Hardness testing machine, used to test the hardness of individual plastic particles;
[0019] Recycling bin for recycling tested plastic particles;
[0020] The transmission mechanism is connected to the hardness testing machine at one end and to the recycling box at the other end, and is used to transmit the single plastic particles transported by the single particle conveying mechanism to the hardness testing machine and transmit the single plastic particles that have completed the test into the recycling box.
[0021] By adopting the above technical solution and integrating a hardness testing machine, a portion of plastic particles can be extracted in real time during the production process of plastic particles, and flowed into the transmission mechanism through the flow port. The transmission mechanism is used to transport the plastic particles to the hardness testing machine to test the hardness of the plastic particles. This can quickly discover and deal with unqualified products, avoid producing a large number of unqualified products, and reduce the time and cost of later testing and rework.
[0022] Optionally, the feeding assembly includes a first driving member and a feeding plate, and the feeding plate is rotatably connected in the discharge channel. The first driving member can drive the feeding plate to rotate, so that one end of the feeding plate connected to the collection box is blocked, and the plastic particles can flow out from the flow port.
[0023] By adopting this technical solution, the feed plate is rotatably connected to the discharge channel, controlling the flow direction of the plastic particles. By rotating the feed plate, the path to the collection box can be selectively blocked, forcing the plastic particles to flow out of the flow port and into the single-particle conveying mechanism. The feed plate cooperates with the first drive member to achieve the automated transfer of plastic particles from the production line to the testing line, reducing manual intervention and improving production efficiency and testing accuracy.
[0024] Optionally, the flow port is rotatably connected to a baffle for closing the flow port, and a connecting rod is provided between the baffle and the feeding plate, one end of the connecting rod is hinged to the baffle, and the other end of the connecting rod is hinged to the feeding plate.
[0025] By adopting this technical solution, the baffle can close the flow port when needed, preventing the outflow of plastic particles. This allows the production line to selectively direct plastic particles to the inspection path or directly into the collection box as needed, providing flexible control over the production process. A connecting rod connects the baffle and the feed plate, enabling them to work in tandem. The first drive element drives the feed plate to rotate, and the connecting rod drives the baffle to move synchronously, ensuring that the opening and closing of the flow port is coordinated with the feeding process.
[0026] Optionally, it further includes a feeding channel, one end of which is connected to the flow port, and the other end of which is connected to the single-grain conveying mechanism.
[0027] By adopting the above technical solution and setting up a feeding channel, it is ensured that the plastic particles can be smoothly transported from the circulation port to the single-particle conveying mechanism, thereby improving the transmission efficiency, avoiding the interference and blockage problems that may occur directly from the circulation port to the single-particle conveying mechanism, and ensuring the continuity and stability of the plastic particle transmission.
[0028] Optionally, the single-particle conveying mechanism includes a vibrating plate, a second driving member, an elastic member, a fixed plate, and a conveying pipe, wherein the vibrating plate is arranged on the fixed plate, the elastic member and the second driving member are both arranged between the vibrating plate and the fixed plate, one end of the elastic member acts on the fixed plate, and the other end of the elastic member acts on the vibrating plate, and the second driving member is used to drive the vibrating plate to vibrate reciprocatingly;
[0029] The vibration plate is provided with a perforation for passing a single plastic particle. One end of the conveying pipe is connected to the perforation, and the other end of the conveying pipe is connected to the transmission mechanism and can convey the plastic particles to the transmission mechanism.
[0030] By adopting the above technical solution, the plastic particles are arranged and transported one by one through vibration, and the plastic particles are transported one by one to the transmission mechanism, and independent detection of the particles is ensured. The plastic particles are individually sampled to achieve control over the quality of the overall plastic particles.
[0031] Optionally, there are several perforations, a accommodating cavity is opened on the fixed plate, a recovery channel is fixedly connected to the side wall of the fixed plate, one end of the recovery channel is connected to the recovery box, and the other end of the recovery channel is connected to the accommodating cavity, and the bottom wall of the accommodating cavity is inclined downward toward the direction of the recovery channel.
[0032] By adopting the above technical solution, the number of plastic particles entering from the circulation port each time is not one, and there is only one plastic particle transmitted to the transmission mechanism. Therefore, the excess plastic particles will accumulate on the vibration plate, which is easy to be confused with the plastic particles entering the vibration plate next time, resulting in inaccurate detection results; by setting multiple perforations, the excess plastic particles will flow into the containing cavity through other perforations and flow into the recycling box through the recycling channel, and the excess plastic particles will be recycled, thereby reducing the confusion of plastic particles and increasing the accuracy of the detection results.
[0033] Optionally, the transmission mechanism includes a transmission track, a slider slidably connected to the transmission track, and a third driving member for driving the slider to slide;
[0034] The slider is provided with a groove, the groove being adapted to the size of the plastic particles and the depth of the groove being less than the height of the plastic particles;
[0035] The transfer track includes a horizontal section and a vertical section, the horizontal section and the vertical section are fixedly connected to each other and the vertical section is inserted into the recovery box;
[0036] There are a loading station and a detection station on the horizontal section. The loading station corresponds to the position of the conveying pipe. When the slider is located at the loading station, the distance between the bottom wall of the groove and the lower end of the conveying pipe is greater than the height of the plastic particles. The groove corresponds to the position of the conveying pipe, so that the plastic particles can fall from the conveying pipe into the groove.
[0037] The detection station corresponds to the position of the hardness testing machine. When the slider slides to the detection station, the plastic particles can be tested.
[0038] When the slider slides from the horizontal section to the vertical section, the plastic particles can fall from the groove into the recycling box.
[0039] By adopting the above technical solution and setting up a transmission track, the transportation of plastic particles can be realized, the plastic particles are transported to the inspection station, and the inspected plastic particles are transported to the recycling box for recycling, thereby reducing the waste of plastic particles.
[0040] Optionally, the feeding mechanism includes a raw material mixing box and a storage box, the raw material mixing box is connected to the storage box, and the storage box is connected to the feed port of the particle extruder.
[0041] By adopting the above technical solution, uniformly mixed raw materials are provided to the particle extruder, ensuring continuous production and storing the mixed raw materials, ensuring continuous feeding of the particle extruder, and improving production efficiency.
[0042] Optionally, the apparatus further includes an electric control mechanism, the electric control mechanism including a controller and a sensor, the sensor being installed in the groove for detecting whether there are plastic particles in the groove, and the controller being electrically connected to the sensor, the hardness detector, the first driving member, the second driving member, and the third driving member respectively;
[0043] When plastic particles exist in the groove, the controller controls the second driving member to stop and controls the third driving member to drive the slider to move to the detection station;

[0048] In summary, this application includes at least one of the following beneficial technical effects:
[0049] 1. By integrating a hardness tester, a portion of plastic particles can be extracted in real time during the production process, flowing into the conveyor mechanism through the flow port. The conveyor mechanism then conveys the plastic particles to the hardness tester for testing the hardness of the plastic particles. This allows for rapid detection and processing of unqualified products, avoiding the production of large quantities of unqualified products and reducing the time and cost of subsequent testing and rework.
[0050] 2. The feed plate is rotatably connected to the discharge channel to control the flow direction of the plastic particles.

[0065] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.
[0066] Reference Figure 1 , a plastic particle production device with product inspection, including a particle extruder 4: responsible for extruding plastic raw materials to form plastic particles; a feeding mechanism 1: providing raw materials for the particle extruder 4 to ensure continuous production; a collecting box 2: used to collect the plastic particles that have been produced; a feeding channel 3: connecting the particle extruder 4 and the collecting box 2, and the plastic particles flow to the collecting box 2 through the feeding channel 3, and a feeding component is provided on the feeding channel 3. A flow port 32 is opened on the side wall of the feeding channel 3 to realize the diversion of plastic particles; a single particle conveying mechanism 5: conveys a single plastic particle to a hardness testing machine 6 to realize random inspection of plastic particles; a hardness testing machine 6: detects the hardness of each plastic particle and records the data; a recycling box 9: collects the plastic particles that have been inspected to ensure that it does not affect the production process and reduces the waste of plastic particles; a transmission mechanism 7: connecting the hardness testing machine 6 and the recycling box 9, used to transmit the items that need to be inspected to the hardness testing machine 6, and transmit the plastic particles that have been inspected into the recycling box 9.
[0067] After a period of time, the feeding component conveys a portion of the plastic particles to the single-particle conveying mechanism 5, which sorts the particles and transmits the single plastic particles to the transmission mechanism 7. The single plastic particles are then transmitted to the hardness tester 6 through the transmission mechanism 7 to test the plastic particles. The tested plastic particles are then transported to the recycling box 9 for recycling through the transmission mechanism.
[0068] The feeding mechanism 1 includes a raw material mixing box 11 and a storage box 12. The raw material mixing box 11 is connected to the storage box 12, and the storage box 12 is connected to the feed port of the particle extruder 4. The raw materials are poured into the raw material mixing box 11 for mixing. The mixed raw materials are transported to the storage box 12 for storage and wait to be transported to the particle extruder 4 for extrusion.
[0069] Reference Figure 2 The feeding assembly includes a first drive member and a feeding plate 311. The feeding plate 311 is rotatably connected to the discharge channel 3. The first drive member can drive the feeding plate 311 to rotate, thereby sealing the end of the feeding plate 311 connected to the collection box 2 and allowing the plastic particles to flow out of the flow port 32. In this embodiment, the first drive member is a motor. The feeding plate 311 is rotatably connected to the discharge channel 3 via a rotating shaft. The first drive member drives the rotating shaft to rotate, thereby driving the feeding plate 311 to rotate.
[0070] The feed plate 311 is sized to fit the discharge channel 3. The end of the flow opening 32 closest to the recovery box 9 is designated as end a. When one end of the feed plate 311 rotates to abut end a, the end of the discharge channel 3 connected to the recovery box 9 is blocked, and the plastic particles flow out of the flow opening 32 and into the single-particle conveying mechanism 5. In other embodiments, when the feed plate 311 abuts end a, the discharge channel 3 may not be blocked, and only a portion of the plastic particles need to be diverted to the single-particle conveying mechanism 5. In other embodiments, the width of the feed plate 311 is smaller than the width of the discharge channel 3.
[0071] The flow port 32 is rotatably connected to a baffle 321 for closing the communication port. A connecting rod 322 is provided between the baffle 321 and the feed plate 311. One end of the connecting rod 322 is hinged to the baffle 321, and the other end of the connecting rod 322 is hinged to the feed plate 311. When the feed plate 311 rotates, the connecting rod 322 moves, causing the connecting rod 322 to rotate the baffle 321, achieving simultaneous rotation of the baffle 321 and the feed plate 311. That is, when it is necessary to detect plastic particles, the baffle 321 rotates to open the flow port 32.
[0072] The side wall of the discharge channel 3 is fixedly connected to a feeding channel 8, and the position of the feeding channel 8 corresponds to the position of the circulation port 32. After the plastic particles pass through the circulation port 32, they flow into the feeding channel 8, and then flow into the single-particle conveying mechanism 5 through the feeding channel 8. The setting of the feeding channel 8 avoids the interference and blockage problems that may occur directly from the circulation port 32 to the single-particle conveying mechanism 5, thereby ensuring the continuity and stability of the plastic particle transmission.
[0073] Reference Figure 3 and Figure 4 The single-particle conveying mechanism 5 includes a vibrating plate 51, a second driving member 52, an elastic member 53, a fixed plate 54 and a conveying pipe 55. The vibrating plate 51 is arranged on the fixed plate 54. The elastic member 53 and the second driving member 52 are both arranged between the vibrating plate 51 and the fixed plate 54. One end of the elastic member 53 acts on the fixed plate 54, and the other end of the elastic member 53 acts on the vibrating plate 51. The second driving member 52 is used to drive the vibrating plate 51 to vibrate reciprocatingly; in this embodiment, the second driving member 52 adopts a vibration motor, which drives the vibrating plate 51 to vibrate up and down repeatedly through the vibration motor. During the vibration of the vibrating plate 51, the elastic member 53 repeatedly undergoes elastic deformation.
[0074] In this embodiment, the elastic member 53 is a spring. There are several springs that are evenly distributed around the vibration plate 51 . Both ends of the springs are fixedly connected to the vibration plate 51 and the fixing plate 54 , respectively.
[0075] Vibrating plate 51 is provided with a perforation 511 for passing a single plastic pellet. One end of a delivery tube 55 is connected to perforation 511, and the other end of the delivery tube 55 is connected to the conveying mechanism 7, capable of conveying the plastic pellets to the conveying mechanism. When a pile of plastic pellets falls into vibrating plate 51, the second drive member 52 rotates, causing the vibrating plate 51 to vibrate repeatedly, forcing a plastic pellet to pass through perforation 511 and flow into delivery tube 55, which then flows to conveying mechanism 7.
[0076] Furthermore, a plurality of perforations 511 are provided, only one of which is connected to the delivery tube 55. A receiving chamber 541 is defined on the fixed plate 54, and a recovery channel 542 is fixedly connected to the sidewall of the fixed plate 54. One end of the recovery channel 542 is connected to the recovery tank 9, and the other end is connected to the receiving chamber 541. During the vibration of the vibrating plate 51, a plurality of plastic particles pass through different perforations 511. When a plastic particle passes through a perforation 511 that is not connected to the delivery tube 55, the plastic particle falls into the receiving chamber 541 and is collected.
[0077] The bottom wall of the accommodating cavity 541 is configured as an inclined surface and is tilted from top to bottom toward the recovery channel 542 , so that the plastic particles falling into the accommodating cavity 541 flow into the recovery box 9 through the recovery channel 542 for collection.
[0078] The transmission mechanism 7 includes a transmission track 71, a slider 72 slidably connected to the transmission track 71 and a third driving member for driving the slider 72 to slide; a groove is provided on the slider 72, the groove is adapted to the size of the plastic particles and the groove depth is less than the height of the plastic particles. In this embodiment, the groove depth is less than half the height of the plastic particles, which facilitates the plastic particles to fall from the groove; in this embodiment, the third driving member adopts a motor and a roller, and the roller is rotatably connected to the slider 72, and the motor drives the roller to rotate, thereby driving the slider 72 to slide on the transmission track 71. In order to reduce the slippage between the roller and the transmission track 71, the roller can be set to a gear shape, and a rack can be set on the side wall of the transmission track 71 so that the rack and the gear are engaged, thereby reducing the slippage between the roller and the transmission track 71.
[0079] The transmission track 71 includes a horizontal section 711 and a vertical section 712. The horizontal section 711 and the vertical section 712 are fixedly connected to each other, and the vertical section 712 is inserted into the recycling box 9. There are a loading station and a detection station on the horizontal section 711. The loading station corresponds to the position of the conveying pipe 55. When the slider 72 is at the loading station, the distance between the bottom wall of the groove and the lower end of the conveying pipe 55 is greater than the height of the plastic particles, and the groove corresponds to the position of the conveying pipe 55, which can cause the plastic particles to fall from the conveying pipe 55 into the groove. In this embodiment, after the plastic particles are inserted into the groove, the distance between them and the conveying pipe 55 is 1mm, thereby reducing the situation where the plastic particles fall into the groove and then pop out of the groove. In other embodiments, after the plastic particles are inserted into the groove, the distance between them and the conveying pipe 55 can also be 0.5mm or other distances, as long as it is ensured that the plastic particles are not easy to fall out of the groove.
[0080] The detection station corresponds to the position of the hardness testing machine 6. When the slider 72 slides to the detection station, the plastic particles can be detected; when the slider 72 slides from the horizontal section 711 to the vertical section 712, the plastic particles can fall from the groove into the recovery box 9.
[0081] Furthermore, a recovery hole is opened on the horizontal section 711, and the recovery hole is located at the loading station position, and a recovery pipe 713 is fixedly connected to the horizontal section 711. One end of the recovery pipe 713 is connected to the recovery hole, and the other end is connected to the recovery box 9. When two plastic particles are continuously transmitted in the conveying pipe 55, the second plastic particle can fall into the recovery hole and flow into the recovery box 9 through the recovery tank for recovery.
[0082] A plastic particle production device with product detection also includes an electric control mechanism, which includes a controller and a sensor. The sensor is fixedly installed in the groove and is used to detect whether there are plastic particles in the groove. The controller is electrically connected to the sensor, hardness testing machine 6, first drive member, second drive member 52 and third drive member respectively. When there are plastic particles in the groove, the controller controls the second drive member 52 to stop and controls the third drive member to drive the slider 72 to move to the detection station; when the plastic particle detection is completed, the controller controls the third drive member to drive the slider 72 to slide to the vertical section 712; when the plastic particles in the groove fall into the recycling box 9, the controller controls the third drive member to drive the slider 72 to slide to the loading station, and when the slider 72 is at the loading station, the controller controls the second drive member 52 to operate; the controller can control the operation of the first drive member at intervals, so that the flow port 32 is repeatedly opened and closed, so as to realize the detection of plastic particles at different time periods.
[0083] The implementation principle of the embodiment of the present application is: first add raw materials into the raw material mixing tank, transport the mixed raw materials to the storage box 12 for storage, and transport the mixed raw materials in the storage box 12 to the particle extruder 4 for particle molding. The molded plastic particles flow into the collection box 2 through the discharge channel 3 for collection.
[0084] During continuous production, the controller controls the first drive member to rotate the feed plate 311, causing some plastic particles to flow into the vibrating disk 51. When some plastic particles still flow into the vibrating disk 51, the controller controls the feed plate 311 to rotate and reset, causing the baffle 321 to close the flow port 32. The vibration of the vibrating disk 51 causes individual particles to flow into the groove through the conveying pipe 55. At this time, the controller controls the third drive member to slide the slider 72, causing the slider 72 to slide to the inspection station. After the hardness tester 6 completes the inspection of the plastic particles, the controller controls the third drive member to slide the slider 72 to the vertical section 712, causing the plastic particles to fall into the recycling bin 9 due to their own gravity for recycling. At this time, the sensor senses that there are no plastic particles in the groove, and then drives the slider 72 to slide to the loading station for the next loading.
[0085] After a period of time, the controller controls the first driving member to operate and repeats the above process, so that the quality of the plastic particles is automatically detected once every period of time, thereby realizing automated detection and ensuring that the overall quality of the plastic particles meets the standards.
