[0002] EPS foaming means that a photoelectric switch for observing EPS foam in the foaming tank is arranged at the glass window of the foaming tank. During production, EPS particles of a fixed weight are put into the foaming tank. During the foaming process, the EPS particles continuously foam and expand, so the height of the EPS foam particles continuously rises in the foaming tank. When it rises to the detection position of the photoelectric switch, it is detected by the photoelectric switch, so that the photoelectric switch acts, stops heating and foaming, and completes a foaming process. During this process, it is necessary to sample and weigh the foamed EPS foam particles to measure and calculate the density of the product;

[0003] In the prior art, the sampling and weighing system is to directly extract the product by a sampler when the EPS foam particles fall into the drying bed after foaming, and perform constant volume weighing in a room temperature environment that is completely different from the higher temperature and higher humidity inside the drying bed; because the characteristics of EPS foam particles determine that the volume of EPS foam particles will change at different temperatures, so the EPS foam particles in the room temperature environment are prone to shrinkage, which leads to the need for more EPS foam particles to fill the constant volume container during constant volume, which also leads to the final weight being higher than the actual value, and it is difficult to accurately measure the actual weight of EPS foam particles in the production equipment; for the above problems, the application number is: 202123288826.7 discloses a full-automatic sampling and weighing device for EPS foam particles, which includes a drying bed body, the top of the drying bed body is provided with a feed inlet, and the inner wall of the drying bed body is fixedly connected with a bracket and a telescopic driving device;

The metering tube 4 is fixedly installed on the mounting plate 3 and corresponds to the foam particle feed inlet 2. Through the cooperative design of the drying bed body 1, the sampling mechanism, the driving mechanism, and the weighing mechanism, not only can the purpose of automatically sampling and weighing the foam particles be achieved, but also the problem that when sampling is carried out through the material receiving port and the feed inlet in the existing sampling work, it is very easy for the foam particles to fall, resulting in waste of resources, and the structure is simple and the practicability is higher.

[0031] In this embodiment, the rotating shaft 5 is rotatably connected to both the mounting plate 3 and the drying bed body 1. A first circular plate 6 is fixedly sleeved on the rotating shaft 5. The top of the first circular plate 6 is in contact connection with the drying bed body 1. The first circular plate 6 is slidably connected to the metering tube 4, achieving the effect of sealing the metering tube 4 and preventing the foam particles from falling.

[0032] In this embodiment, a first through hole 14 is formed in the first circular plate 6. The first through hole 14 corresponds to the metering tube 4 and the foam particle feed inlet 2, facilitating the sampling of the foam particles.

[0033] In this embodiment, a second circular plate 7 is fixedly sleeved on the rotating shaft 5. The second circular plate 7 is slidably connected to the metering tube 4, facilitating the quantitative sampling of the foam particles.

[0034] In this embodiment, a second through hole 15 is formed in the second circular plate 7. The second through hole 15 is adapted to the metering tube 4, facilitating the sampled foam particles to enter the weighing bucket 9.

[0035] In this embodiment, the weighing mechanism includes a weight sensor 8 and a weighing bucket 9. The weight sensor 8 is provided on the mounting plate 3, and the weighing bucket 9 is provided on the weight sensor 8. The weighing bucket 9 is adapted to the metering tube 4 and is used to weigh the sampled foam particles, thereby measuring and calculating the density of the product.

[0036] In this embodiment, the driving mechanism includes a motor 10, a first gear 11, and a second gear 12. The motor 10 is fixedly connected to the mounting plate 3. The output end of the motor 10 is fixedly connected to the first gear 11. The first gear 11 is meshed with the second gear 12, and the second gear 12 is fixedly connected to one end of the rotating shaft 5 for driving the sampling mechanism.

[0037] In this embodiment, a first groove 16 is formed in the metering tube 4, and the first circular plate 6 rotates in the first groove. A second groove 17 is formed in the metering tube 4, and the second circular plate 7 rotates in the second groove, facilitating the rotation of the first circular plate 6.

[0038] In this embodiment, a third groove is formed in the metering tube 4. The third groove corresponds to the weighing bucket 9, facilitating the rotation of the second circular plate 7.

[0039] In this embodiment, a box door 13 is provided on the drying bed body 1. The box door 13 corresponds to the weighing mechanism box, which facilitates the removal of the weighing bucket 9 and enables the temperature inside the drying bed body 1 to match the temperature of the foam particles. For the specific structure and working principle of the drying bed body 1, please refer to the document with the application number: 202123288826.7 proposed in this application. This is prior art and will not be elaborated further.

[0040] Working principle: During use, the drive of the motor 10 causes the first gear 11 to rotate and transmit power to the second gear 12. At the same time, the second gear 12 drives the rotating shaft 5 to rotate on the mounting plate 3 and the drying bed body 1. Meanwhile, the rotating shaft 5 drives the first circular plate 6 and the second circular plate 7 to rotate synchronously. During this process, when the through hole 14 on the first circular plate 6 corresponds to the foam particle inlet 2 on the drying bed body 1, the foam particles pass through the foam particle inlet 2 and the through hole 14 and enter the metering tube 4, thus achieving the effect of automatic sampling.

[0041] Then, the motor 10 drives again, causing the through hole 14 to disengage from the metering tube 4 and the foam particle inlet 2, thereby achieving the sealing effect of the metering tube 4. At the same time, the through hole 15 on the second circular plate 7 corresponds to the metering tube 4 and the weighing bucket 9, so that the foam particles in the metering tube 4 fall into the weighing bucket 9. Then, the weight sensor 8 weighs the foam particles in the weighing bucket 9, thus achieving the effect of automatic sampling and weighing of the foam particles.

[0042] Since the top of the first circular plate 6 is in contact with the drying bed body 1, it prevents the foam particles from falling during the weighing process of the sampled foam particles, thereby preventing waste of resources.

[0043] After weighing, open the box door 13 and take out the weighing bucket 9.

[0044] In summary, the entire sampling and volume determination process is carried out inside the drying bed body, ensuring that the temperature of the sample weighing is the same as the temperature inside the drying bed body. In this way, the volume of the volumetric foam particles will not shrink, and the weighing accuracy is significantly increased, effectively reducing the measurement deviation.

[0045] The technical progress obtained by this utility model compared with the prior art is that through the cooperation of various components, it can not only achieve the purpose of automatic sampling and weighing of foam particles, but also solve the problem that when sampling is carried out through the material receiving port and the feeding port in the prior art, foam particles are likely to fall, resulting in waste of resources. Moreover, the structure is simple and the practicality is higher.
