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 particles refer to small particles made of plastic raw materials. They are widely used in industrial production. These particles are usually produced through plastic processing and granulation processes and are used to make various plastic products.

[0003] The production of plastic pellets usually requires the use of a plastic pellet production device, which includes: Feeding system: Plastic raw materials are usually fed into the production line in the form of pellets, granules or powder. The feeding system includes a conveyor belt, bucket elevator or vacuum conveying system, etc., which is used to transport the raw materials from the storage bin or bag to the production line.

[0004] Plasticizer (Extruder): Plasticizer is a device that heats, melts and plasticizes plastic raw materials into a continuous and uniform melt. Plasticizers are usually composed of a feeding section, a screw, a heating / cooling area and an extruder. In the plasticizer, the plastic raw materials are heated above the melting point and the melt is extruded by the rotation of the screw.

[0005] Pelletizer: Pelletizer is used to cut the continuously extruded plastic melt into solid particles. Pelletizer usually includes cutting tools, cooling water pool and conveying system. After the melt is extruded from the extruder, it is cut into particles of a predetermined length by the cutting tool, cooled and solidified by the cooling water pool, and finally collected and transported to the subsequent processing equipment by the conveying system.

[0006] Cooling system: During the granulation process, the cooling system is used to quickly cool the melt and solidify it into particles, and control the temperature of the particles 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 particles meet the specification requirements.

[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 a hardness testing device for testing.

[0008] However, testing is often done after a batch of products has been produced. If defective products are discovered at this time, the losses caused have already been huge, and there is a problem of not being able to test 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 solution: A plastic particle production device with product detection, comprising: A pellet extruder is used to extrude raw materials into plastic pellets; A feeding mechanism, connected to the particle extruder and used for feeding the particle extruder; A collection box for collecting the finished plastic particles; A material 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 opening height of the collection box; A flow opening is provided on the side wall of the material discharge channel, and a feeding assembly for discharging plastic particles from the flow opening is installed on the material discharge channel; A single-particle conveying mechanism is installed on the side of the discharge channel where the flow opening exists and is used to convey one of the plurality of plastic particles; Hardness testing machine, used to test the hardness of individual plastic particles; Recycling bins for recycling tested plastic particles; The transmission mechanism is connected to the hardness tester at one end and to the recovery box at the other end, and is used to transmit the single plastic particle transported by the single particle transport mechanism to the hardness tester and to transmit the tested single plastic particle into the recovery box.

[0011] 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 flow 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 inspection and rework.

[0012] 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.

[0013] By adopting the above technical solution, the feed plate is rotatably connected in the feeding channel, which can control the flow direction of the plastic particles. By rotating the feed plate, the path leading to the collection box can be selectively blocked, forcing the plastic particles to flow out of the flow port and enter the single-particle conveying mechanism. The cooperation between the feed plate and the first driving member realizes the automatic transfer of plastic particles from the production line to the detection line, reduces manual intervention, and improves production efficiency and detection accuracy.

[0014] Optionally, the flow port is rotatably connected to a baffle for closing the flow port, 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.

[0015] By adopting the above technical solution, the baffle can close the flow port when necessary to prevent the plastic particles from flowing out. This allows the production line to selectively guide the plastic particles to the detection path or directly into the collection box as needed, and flexibly control the production process. The connecting rod connects the baffle and the feed plate to achieve the coordinated work of the two. The feed plate is driven to rotate by the first driving member, and the connecting rod drives the baffle to move synchronously to ensure that the opening and closing of the flow port is coordinated with the feeding process.

[0016] Optionally, it further comprises 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.

One end of the conveying pipe is connected to the through hole, and the other end of the conveying pipe is connected to the transmission mechanism and can convey the plastic particles to the transmission mechanism.

[0019] By adopting the above technical solution, the plastic particles are arranged and transmitted one by one through vibration, and the plastic particles are transmitted to the transmission mechanism one by one, and independent detection of the particles is ensured, and individual spot checks are performed on the plastic particles to control the quality of the overall plastic particles.

[0021] 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, excess plastic particles will accumulate on the vibration plate, which may be easily confused with the plastic particles entering the vibration plate next time, resulting in inaccurate detection results. By setting a plurality of perforations, excess plastic particles flow into the containing cavity through other perforations and flow into the recovery box through the recovery channel, so that the excess plastic particles are recovered, thereby reducing the confusion of plastic particles and increasing the accuracy of the detection results.

[0022] 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; The slider is provided with a groove, the groove is adapted to the size of the plastic particles and the depth of the groove is less than the height of the plastic particles; The transfer track comprises 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; 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 inner bottom wall of the groove and the lower end of the conveying pipe is greater than the height of the plastic particles and the groove corresponds to the position of the conveying pipe, so that the plastic particles can fall from the conveying pipe into the groove; The detection station corresponds to the position of the hardness testing machine, and when the slider slides to the detection station, the plastic particles can be tested; When the slide block slides from the horizontal section to the vertical section, the plastic particles can fall from the groove into the recycling box.

[0034] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0035] Reference Figure 1, a plastic particle production device with product detection, 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, the plastic particles flow to the collecting box 2 through the feeding channel 3, the feeding channel 3 is provided with a feeding component, and the side wall of the feeding channel 3 is provided with a flow port 32 for realizing the diversion of plastic particles; a single particle conveying mechanism 5: conveying a single plastic particle to a hardness testing machine 6 to realize the random inspection of plastic particles; the hardness testing machine 6: detecting the hardness of each plastic particle and recording the data; a recycling box 9: collecting the plastic particles that have been tested to ensure that the production process is not affected and the waste of plastic particles is reduced; a transmission mechanism 7: connecting the hardness testing machine 6 and the recycling box 9, used to transmit the items to be tested to the hardness testing machine 6, and transmit the plastic particles that have been tested into the recycling box 9.

[0036] After a period of time, the feeding component conveys a part of the plastic particles to the single-particle conveying mechanism 5, and the single-particle conveying mechanism 5 sorts out a number of particles, and transmits a single plastic particle to the transmission mechanism 7, and then transmits it to the position of the hardness testing machine 6 through the transmission mechanism 7 to test the plastic particles. Then, the tested plastic particles are transported to the recycling box 9 for recycling through the conveying mechanism.

[0037] 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 material is poured into the raw material mixing box 11 for mixing, and the mixed raw material is transported to the storage box 12 for storage, waiting to be transported to the particle extruder 4 for extrusion.

[0038] Reference Figure 2 The feeding assembly includes a first driving member and a feeding plate 311, the feeding plate 311 is rotatably connected in the material discharge channel 3, and the first driving member can drive the feeding plate 311 to rotate, so that the end of the feeding plate 311 communicating with the collecting box 2 is blocked, and the plastic particles can flow out from the flow port 32. In this embodiment, the first driving member is a motor, and the feeding plate 311 is rotatably connected in the material discharge channel 3 through a rotating shaft. The first driving member drives the rotating shaft to rotate, thereby driving the feeding plate 311 to rotate.

[0039] The size of the feed plate 311 is adapted to the material discharge channel 3, and the end of the flow port 32 close to the recycling box 9 is named end a. When one end of the feed plate 311 rotates to abut against end a, the end of the material discharge channel 3 connected to the recycling box 9 is blocked, and the plastic particles flow out of the flow port 32 and flow into the single-particle conveying mechanism 5. In other embodiments, when the feed plate 311 abuts against end a, the material discharge channel 3 may not be blocked, and only a part of the plastic particles need to be diverted to the single-particle conveying mechanism 5, that is, the width of the feed plate 311 is smaller than the width of the material discharge channel 3.

[0040] The flow port 32 is rotatably connected to a baffle 321 for closing the communication port, and a connecting rod 322 is provided between the baffle 321 and the feeding 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 feeding plate 311. When the feeding plate 311 rotates, the connecting rod 322 is driven to move, so that the connecting rod 322 drives the baffle 321 to rotate, so that the baffle 321 and the feeding plate 311 rotate simultaneously, that is, when it is necessary to detect plastic particles, the baffle 321 rotates to open the flow port 32.

[0041] A feeding channel 8 is fixedly connected to the side wall of the discharge channel 3, 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. Through the setting of the feeding channel 8, possible interference and blockage problems directly from the circulation port 32 to the single-particle conveying mechanism 5 are avoided, thereby ensuring the continuity and stability of the plastic particle transmission.

[0042] Reference Figure 3 and Figure 4 The single-particle conveying mechanism 5 includes a vibration plate 51, a second driving member 52, an elastic member 53, a fixed plate 54 and a conveying pipe 55. The vibration plate 51 is arranged on the fixed plate 54. The elastic member 53 and the second driving member 52 are both arranged between the vibration 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 vibration plate 51. The second driving member 52 is used to drive the vibration plate 51 to vibrate reciprocatingly. In this embodiment, the second driving member 52 adopts a vibration motor, which drives the vibration plate 51 to vibrate up and down repeatedly through the vibration motor. During the vibration of the vibration plate 51, the elastic member 53 repeatedly undergoes elastic deformation.

[0043] In this embodiment, the elastic member 53 is a spring. There are a plurality of springs, which 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.

[0044] The vibration plate 51 is provided with a through hole 511 for passing a single plastic particle. One end of the delivery pipe 55 is connected to the through hole 511, and the other end of the delivery pipe 55 is connected to the transmission mechanism 7 and can deliver the plastic particles to the transmission mechanism. When a pile of plastic particles falls into the vibration plate 51, the second driving member 52 operates to drive the vibration plate 51 to vibrate repeatedly, so that a plastic particle passes through the through hole 511 and flows into the delivery pipe 55, and then flows into the transmission mechanism 7 through the delivery pipe 55.

[0045] Furthermore, a plurality of perforations 511 are provided, and only one of the perforations 511 is connected to the delivery pipe 55. A receiving chamber 541 is provided on the fixed plate 54, and a recovery channel 542 is fixedly connected to the side wall of the fixed plate 54. One end of the recovery channel 542 is connected to the recovery box 9, and the other end is connected to the receiving chamber 541. During the vibration of the vibration plate 51, a plurality of plastic particles pass through different perforations 511 respectively. When the perforations 511 passed by the plastic particles are not connected to the delivery pipe 55, the plastic particles fall into the receiving chamber 541 for collection.

[0046] The inner bottom wall of the accommodating cavity 541 is arranged as an inclined surface and is inclined from top to bottom toward the recovery channel 542 , so that the plastic particles dropped into the accommodating cavity 541 flow into the recovery box 9 through the recovery channel 542 for collection.

[0047] 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 depth of the groove is less than the height of the plastic particles. In this embodiment, the depth of the groove 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, the roller is rotatably connected to the slider 72, 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 is set on the side wall of the transmission track 71, so that the rack is meshed with the gear, thereby reducing the slippage between the roller and the transmission track 71.

[0048] 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 located 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, so that the plastic particles can 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 pop out of the groove after falling into 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.

[0049] 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.

[0050] Furthermore, a recovery hole is opened on the horizontal section 711, and the recovery hole is located at the loading station, 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.

[0051] 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 detection 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 located 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 in different time periods.

[0052] 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, transport the mixed raw materials in the storage box 12 to the particle extruder 4 for particle forming, and the formed plastic particles flow into the collection box 2 through the discharge channel 3 for collection.

[0053] During the continuous production process, the controller controls the first driving member to drive the feeding plate 311 to rotate, so that some plastic particles flow into the vibration disk 51. When some plastic particles flow into the vibration disk 51, the controller controls the feeding plate 311 to rotate and reset, so that the baffle 321 closes the flow port 32; through the vibration of the vibration disk 51, the single particle flows into the groove through the conveying pipe 55. At this time, the controller controls the third driving member to drive the slider 72 to slide, so that the slider 72 slides to the detection station; after the hardness tester 6 completes the detection of the plastic particles, the controller controls the third driving member to drive the slider 72 to slide to the vertical section 712, so that the plastic particles fall into the recycling box 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.

[0054] After a certain 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 after a certain period of time, and automatic detection is realized to ensure that the overall quality of the plastic particles meets the standards.

[0055] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
