Description

Technical Field

[0001] The utility model relates to the technical field of foam particle collection, in particular to a foam particle collection device. Background Art

[0002] Foam particles are high molecular polymers. The foam particles that keep you warm in winter and cool in summer are fluid and more comfortable when filled in pillows. The filled EPS particles can adjust to keep you warm in winter and cool in summer according to the indoor temperature. In the related technology, the pre-expanded foam particles enter a vulcanizing bin where a vulcanizing bed is installed. One side of the vulcanizing bin is connected to a collection device for the foam particles, which is used to collect the foam particles.

[0003] According to the Chinese patent with announcement number: CN214163722U, a foam particle collection device includes a collection bin, which is connected to a vulcanization bin, a vulcanization bed is installed in the vulcanization bin, foam particles are transmitted on the surface of the vulcanization bed by wind, a feeding net is installed in the collection bin for screening out large-diameter foam particles stuck together, and the collection bin at the bottom of the feeding net is connected to a collection tank for collecting foam particles.

[0004] In the above scheme, the particles are heated in the vulcanizing bin to foam into foam particles. However, the above scheme still has the following disadvantages: the rotation of the scraper generates a large wind resistance, which may cause the produced foam particles to be unable to enter the collecting bin due to the wind resistance, resulting in low efficiency in collecting the foam particles. Utility Model Content

[0005] The utility model aims to provide a foam particle collecting device to solve the problem that the rotation of the scraper generates large wind resistance, which may cause the produced foam particles to be unable to enter the collecting bin due to the wind resistance, resulting in low efficiency of foam particle collection.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a foam particle collection device, including a shell, a buffer block is fixed to the inner bottom of the shell, a PLC controller is fixed to the front side of the shell, a screen is fixed to the right top surface of the buffer block, a support rod is fixed to the right top surface of the buffer block, a drive motor is fixed to the top of the support rod, a scraper is fixed to the output end of the drive motor, the output end of the drive motor passes through the screen and is connected to the scraper, and the drive motor is electrically connected to the PLC controller.

[0007] Preferably, a temperature sensor is fixed to the inner wall of the shell, a heating plate is fixed to the inner bottom of the shell, and both the temperature sensor and the heating plate are electrically connected to the PLC controller.

[0008] Preferably, a water outlet is provided on the lower side of the buffer block, a water inlet is provided on the lower side of the buffer block, the bottom surfaces of the water outlet and the water inlet are on the same level as the top surface of the heating plate, and a feed inlet is provided on the front side of the shell.

[0009] Preferably, a first fixing hole is opened on the left side of the shell, a first fan is fixed to the first fixing hole, and the first fan is electrically connected to the PLC controller.

[0010] Preferably, a second fixing hole is opened on the upper side of the shell, a second fan is fixed to the second fixing hole, and the second fan is electrically connected to the PLC controller.

[0011] Preferably, a material discharge net is fixed on the top surface of the buffer block, a material receiving bin is arranged below the material discharge net, an observation window is fixed on the front side of the shell, and an air pressure net is fixed on the right side of the shell.

[0012] Compared with the prior art, a foam particle collection device using the above technical solution has the following features:

[0013] Beneficial effects:

[0014] 1. During use, the scraper is thin and the rotating surface is narrow. The driving motor drives the scraper to rotate without generating large wind resistance, which will not cause the foam particles to be unable to enter the screen. The rotation of the scraper reduces the adhesion of the foam particles. The foam particles can enter the collecting bin only after passing through the feeding net. The two screenings make the collected foam particles in an independent state, which improves the efficiency of collecting foam particles.

[0015] 2. During use, the real-time temperature in the foaming chamber is detected by the temperature sensor, and the temperature sensor transmits the temperature signal to the PLC controller. If the temperature is low, the PLC controller controls the heating plate to heat it. When the temperature is high, the PLC controller controls the heating plate to stop heating, ensuring that the temperature in the foaming chamber is at the optimal temperature for foaming of the pre-foamed material, reducing the probability of defective foam particles and ensuring the stability of the collected foam particles.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, a foam particle collecting device includes an outer shell 1, a buffer block 2 is fixed to the inner bottom of the outer shell 1, a temperature sensor 3 is fixed to the inner wall of the outer shell 1, a heating plate 4 is fixed to the inner bottom of the outer shell 1, a PLC controller 5 is fixed to the front side of the outer shell 1, the temperature sensor 3 and the heating plate 4 are electrically connected to the PLC controller 5, a water outlet 6 is opened on the lower side of the buffer block 2, a water inlet 7 is opened on the lower side of the buffer block 2, the bottom surfaces of the water outlet 6 and the water inlet 7 are on the same horizontal plane with the top surface of the heating plate 4, a feed port 8 is opened on the front side of the outer shell 1, a first fixing hole 9 is opened on the left side of the outer shell 1, a first fan 10 is fixed to the first fixing hole 9, and the first fan 10 is electrically connected to the PLC controller 5.

[0023] During use, the staff injects water into the foaming chamber through the water inlet 7, and the water level in the foaming chamber gradually rises until the water level reaches the inclined position of the buffer block 2, stops injecting water into the foaming chamber and closes the water inlet 7. The staff starts the heating plate 4 in the foaming chamber through the PLC controller 5, and the heating plate 4 heats the water in the foaming chamber. When the water temperature in the foaming chamber reaches the optimal temperature for foaming, the temperature sensor 3 in the foaming chamber transmits the temperature signal to the PLC controller 5, and the PLC controller 5 controls the heating plate 4 to stop heating. At this time, the pre-foamed material is taken out of the foaming chamber. The feed port 8 pours into the foaming bin. The pre-foamed material is at the bottom of the water due to its density. When the density of the pre-foamed material decreases after foaming, the foam particles will float to the surface of the water. At this time, the staff controls the first fan 10 to rotate through the PLC controller 5. The wind force of the first fan 10 pushes the foam particles to move toward the screen 11. At the same time, the first fan 10 plays the role of the first cooling. Since the top surface of the buffer block 2 is at an angle of 135 degrees to the screen, the first fan 10 is effectively prevented from blowing water into the receiving bin 18, thereby improving the stability of the collecting device.

[0024] like Figure 1-Figure 4As shown, a screen 11 is fixed to the top surface of the right side of the buffer block 2, a support rod 12 is fixed to the top surface of the right side of the buffer block 2, a drive motor 13 is fixed to the top of the support rod 12, a scraper 14 is fixed to the output end of the drive motor 13, the output end of the drive motor 13 passes through the screen 11 and is connected to the scraper 14, the drive motor 13 is electrically connected to the PLC controller 5, a second fixing hole 15 is opened on the upper side of the outer shell 1, a second fan 16 is fixed to the second fixing hole 15, and the second fan 16 is electrically connected to the PLC controller 5, a feeding net 17 is fixed to the top surface of the buffer block 2, a material receiving bin 18 is arranged below the feeding net 17, an observation window 19 is fixed to the front side of the outer shell 1, and an air pressure net 20 is fixed to the right side of the outer shell 1.

[0025] During use, the staff controls the driving motor 13 to work through the PLC controller 5, and the scraper 14 of the driving motor 13 rotates on the screen 11. Since the scraper 14 is thin, a small wind force is generated when the scraper 14 rotates, and the foam particles will not be caused to move away from the screen 11. When some foam particles are adhered together, the scraper 14 crushes the adhered foam particles into separate particles. At this time, the separate foam particles can just pass through the screen 11. The second fan 16 is controlled to work through the PLC controller 5, and the wind force generated by the second fan 16 pushes the foam particles. The foam particles pass through the discharge net 17 into the collecting bin 18, and the second fan 16 plays a second cooling effect. The air pressure net 20 on the right side of the outer shell 1 stabilizes the air pressure inside the device, and the air pressure will not rise due to heating water. At the same time, the wind force generated by the first fan 10 and the second fan 16 effectively pushes the foam particles, ensuring the stability of the device. The staff can observe the collection of foam particles through the observation window 19 on the front side of the outer shell 1. If the collected foam particles are deformed or discolored, they can be discovered and adjusted in time to ensure production efficiency.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
