[0002] In the production and application of EPP particles, EPP particles are widely used in many industries such as automotive parts, packaging materials, building insulation, and toy manufacturing due to their excellent cushioning performance, thermal insulation, chemical resistance, and recyclability. As downstream industries continue to raise their product performance requirements, quality control of EPP particles has become a core aspect of the production process, and particle density is a key indicator for measuring its quality. During the production process, EPP particles, after extrusion and foaming, are typically transported to storage equipment or packaging stages via a feed pipe. The state of the particles transported inside the feed pipe directly reflects the quality of the current production batch. Therefore, setting up sampling points on the feed pipe and performing real-time, accurate sampling is a necessary means to monitor production stability, ensure the reliability of downstream processing, meet quality traceability and compliance requirements, and optimize production efficiency. Therefore, there is an urgent need for a material sampling device that can sample the material from the feed tube to ensure the stable and controllable production process of EPP particles and the reliable achievement of product quality standards.

[0018] Reference Figure 1-4 This application proposes an embodiment of the material sampling device using a discharge tube, which includes: The material discharge box 10 has an open top and its lower end is connected to one end of the recovery pipe 20 via a one-way valve. The other end of the recovery pipe 20 is connected to the inside of the material discharge pipe 30. A material discharge funnel 40 is installed on the material discharge box 10 and located above the opening. The sampling tube 50 has one end connected to the inside of the discharge tube 30 and the other end extended to the top of the discharge funnel 40. The sampling tube 50 is equipped with a discharge valve 60. The conveying device 70 is connected to the inside of the recycling pipe 20 and is used to send air into the recycling pipe 20 to send the foamed beads in the discharge box 10 back into the discharge pipe 30.

[0019] When sampling the foamed particles in the discharge tube 30 is required, first open the discharge valve 60 on the sampling tube 50. The foamed particles in the discharge tube 30 will flow naturally through the sampling tube 50 and be transported to the top of the discharge funnel 40 by gravity, and then fall precisely into the discharge box 10 below through the discharge funnel 40. If a specific amount of sample needs to be collected, hold the sampling cup 90 with a certain volume and place it into the discharge box 10, allowing the foamed particles to fall directly into the sampling cup 90 and accumulate naturally. After reaching the preset sampling amount, close the discharge valve 60 to complete the sampling, thereby calculating the density of the foamed particles in the discharge tube 30. After sampling, the foamed particles in the sampling cup 90 are poured back into the sampling box. The conveying device 70 is started to send air into the recovery pipe 20. The foamed particles in the discharge box 10 will flow along the recovery pipe 20 and eventually return to the discharge pipe 30. The foamed particles continue to fall along the recovery pipe 20 and the discharge pipe 30 to storage or packaging.

[0020] The conveying device 70 includes a fan and an air supply pipe. The air outlet of the fan is connected to one end of the air supply pipe, and the other end of the air supply pipe is connected to the recovery pipe 20.

[0021] The sampling device for the discharge pipe described in this application can sample the foamed particles in the discharge pipe 30 at any time through the discharge valve 60, and use the discharge funnel 40 to allow the foamed particles to fall freely under gravity into the discharge box 10. This makes it convenient for the staff to hold the sampling cup 90 and take samples below the discharge funnel 40. The staff can calculate the density of the foamed beads based on the mass and volume of the foamed beads in the sampling cup 90, which helps to ensure the stability and controllability of the EPP particle production process and the reliable achievement of product quality standards.

[0022] Preferably, the material discharge box 10 is a transparent box, which makes it easy for staff to observe the flow of materials and the sampling situation.

[0023] Preferably, the material box 10 is also provided with a support platform 80, on which the sampling cup 90 is placed, so that the staff can place the sampling cup 90.

[0024] Specifically, the carrying platform 80 includes multiple horizontal bars 81 fixedly installed inside the material drop box 10. The multiple horizontal bars 81 are arranged in a ring inside the material drop box 10. The sampling cup 90 has an outward flange at its upper end, and the sampling cup 90 is placed on the multiple horizontal bars 81 through the outward flange.

[0025] The multiple horizontal bars 81 inside the material feeding box 10 are arranged in a ring to form a stable support structure. The sampling cup 90 is mounted on the horizontal bars 81 by the outer flange at the top. The contact area between the outer flange and the horizontal bars 81 is uniform, ensuring that the sampling cup 90 remains stable during the process of receiving particles and will not shift or tilt due to material impact.

[0026] Preferably, the upper end of the outward-flared edge is a conical surface.

[0027] The conical surface prevents the foamed beads from accumulating on the upper end of the outer flange and affecting the accuracy of density detection. The conical surface can be an inner conical surface or an outer conical surface. Referring to the attached figure, the upper end of the outer flange is an inner conical surface so that the foamed beads at the upper end of the outer flange fall into the sampling cup 90. In another embodiment, the upper end of the outer flange is an outer conical surface so that the foamed beads at the upper end of the outer flange fall into the material box 10.

[0028] Preferably, the supporting platform 80 is equipped with a mass detection device 100 for weighing the sampling cup 90. After sampling is completed, the mass detection device 100 is activated and the mass of the sampled sampling cup 90 is detected. The staff can then know the mass of the foamed beads in the sampling cup 90 based on the detection results of the mass detection device 100, which facilitates the calculation of density.

[0029] Those skilled in the art should know that the material box 10 is equipped with a display, which is connected to the quality inspection device 100 and used to display the inspection results of the quality inspection device 100.

[0030] After sampling is completed within the sampling cup 90, the quality detection device 100 is restarted to avoid impact on the quality detection device 100 during the feeding of foamed beads, which would cause errors.

[0031] In this embodiment, the quality detection device 100 includes multiple pressure sensors, which are respectively installed on the upper ends of multiple horizontal rods 81. The sampling cup 90 is placed on the multiple horizontal rods 81 by means of an outward flange and is in contact with the multiple pressure sensors.

[0032] When EPP particles fall freely from the discharge pipe 30 into the sampling cup 90, they naturally accumulate under the influence of gravity, and the total mass of the sampling cup 90 gradually increases as the number of particles increases. Since the outer flange of the sampling cup 90 is in direct contact with the pressure sensor on the horizontal rod 81, the increased mass is converted into a pressure signal and transmitted to the sensor. The pressure sensor converts the mechanical signal into an electrical signal, providing real-time feedback on the cumulative mass of particles in the sampling cup 90.

[0033] Preferably, the sampling cup 90 includes a cup body 91 and a cup bottom 92. The lower end of the cup body 91 is provided with a discharge port, the upper end of the cup body 91 is open and has an outward flange, one side of the cup bottom 92 is hinged to the lower end of the cup body 91, and the other side is connected to the cup body 91 through a detachable connecting mechanism 93.

[0034] In this embodiment, the other side of the cup bottom 92 is detachably connected to the cup body 91. After sampling is completed, the quality inspection device 100 performs quality inspection on the foamed beads in the cup body 91. Then, the operator can operate the detachable connection mechanism 93 to disconnect the cup body 91 and the cup bottom 92, so that the cup bottom 92 opens the discharge port. The foamed beads in the cup body 91 fall into the discharge box 10 through the discharge port. Then, the cup body 91 and the cup bottom 92 are reconnected, and the next sampling operation can be performed.

[0035] Referring to the attached drawings, the material box 10 is provided with an operating hole, and an operating door 11 that can be opened and closed is provided at the operating hole. After the operating door 11 is opened, it is convenient for the staff to connect or disconnect the cup bottom 92 from the cup body 91.

[0036] In this embodiment, the detachable connection mechanism 93 includes a snap-fit ​​mechanism, a latch mechanism, etc., and as shown in the accompanying drawings, the detachable connection mechanism 93 is a snap-fit ​​mechanism.

[0037] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
