[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model provides an automatic feeding device for foam processing, such as Figure 1-4 As shown, the automatic feeding device for foam processing includes: an air pump 1; a first threaded barrel 2, which is rotatably mounted on the air inlet end of the air pump 1; a side fixed pipe 3, which is threadedly mounted on the first threaded barrel 2; a buffer box 4, which is mounted on the side fixed pipe 3; a feed pipe 5, which is fixedly mounted on the side of the buffer box 4 away from the side fixed pipe 3; a second threaded barrel 6, which is threadedly mounted on the feed pipe 5; a material guide pipe 7, which is rotatably mounted on the second threaded barrel 6, and a suction head 8 is installed on the material guide pipe 7; a discharge assembly, which is arranged on the buffer box 4, and the discharge assembly is used to assist in discharging the foam ball raw materials.

[0022] In this embodiment, the vacuum pump 1 is the power source of the device, which is used to generate airflow to drive the foam balls to be transported in the pipeline. The design of the first threaded tube 2 makes it easy to adjust the connection between the side fixed tube 3 and the vacuum pump 1. The buffer box 4 plays the role of buffering and storing the foam balls. During the foam ball transportation process, the foam balls in the buffer box 4 form a certain accumulation, which can continuously and stably supply foam balls to the mold. At the same time, the buffer box 4 can be used to add foam balls in a quantitative manner.

[0023] In a further preferred embodiment of the utility model, the discharging assembly includes a discharging barrel 17, two second electric telescopic rods 14, a baffle 15 and a fan 20, the discharging barrel 17 is fixedly mounted on the bottom of the buffer box 4, the two second electric telescopic rods 14 are respectively fixedly mounted on the side fixed tube 3 and the feed pipe 5, the baffle 15 is fixedly mounted on the output rods of the two second electric telescopic rods 14, the fan 20 is fixedly mounted on the top of the buffer box 4, and the exhaust end of the fan 20 extends into the buffer box 4.

[0024] In this embodiment, the discharge barrel 17 serves as the outlet for discharging the foam balls. The discharge of the foam balls can be precisely controlled by controlling the switch state of the discharge barrel 17. The position of the baffle 15 can be adjusted by controlling the extension and retraction of the second electric telescopic rod 14, thereby changing the outlet size of the foam balls in the buffer box 4 to achieve the discharge of the foam balls. The function of the fan 20 is to generate airflow to push the foam balls in the buffer box 4 toward the discharge barrel 17, thereby achieving rapid discharge of the foam balls.

[0025] In a further preferred embodiment of the utility model, isolation nets are provided in the side fixed tube 3 and the exhaust duct of the fan 20, the buffer box 4 is made of transparent glass, and the outer walls of the first threaded tube 2 and the second threaded tube 6 are provided with anti-slip patterns.

[0026] In this embodiment, the main function of the isolation net is to prevent the foam balls from being sucked into the pipeline during the transmission process, causing blockage or damage to the equipment. At the same time, the isolation net can also play a filtering role, blocking possible impurities or particulate matter, ensuring the purity and stability of the airflow. The transparent glass material makes the number and status of the foam balls in the buffer box 4 clear at a glance, which is convenient for the operator to observe and adjust at any time. The transparent glass material also has the advantages of corrosion resistance and easy cleaning, which can ensure that the device maintains a good working condition during long-term use. The anti-slip pattern can increase the friction of the operator when adjusting the first threaded barrel 2 and the second threaded barrel 6, preventing the threaded barrel from loosening or shifting due to hand slippage or improper operation, which not only improves the accuracy and stability of the operation, but also reduces the safety risks caused by operational errors.

[0027] In a further preferred embodiment of the utility model, the feed pipe 5 is composed of a mounting pipe 9 and a connecting pipe 10, the mounting pipe 9 is fixed on the buffer box 4, the connecting pipe 10 is threadedly installed in the second threaded tube 6, a connecting frame 11 is fixedly installed between the mounting pipe 9 and the connecting pipe 10, a first electric telescopic rod 12 is fixedly installed on the connecting frame 11, an adjusting plate 13 is fixedly installed on the output rod of the first electric telescopic rod 12, an opening 19 is provided on the adjusting plate 13, and the opening 19 can be located between the mounting pipe 9 and the connecting pipe 10.

[0028] In this embodiment, the connecting frame 11 not only plays a role of connection and fixing, but also provides a mounting platform for mounting the first electric telescopic rod 12. When the opening 19 is located between the mounting tube 9 and the connecting tube 10, the foam ball can enter the connecting tube 10 from the mounting tube 9 through the opening 19, and then enter the mold. When the opening 19 is not located between the mounting tube 9 and the connecting tube 10, the foam ball cannot pass through. By controlling the extension and retraction of the first electric telescopic rod 12, the position of the adjustment plate 13 can be adjusted, thereby changing the position of the opening 19.

[0029] In a further preferred embodiment of the present invention, silicone rings are fixedly mounted on one side of the mounting tube 9 and the connecting tube 10 that are close to each other, and the two silicone rings can contact the two sides of the adjustment plate 13 respectively.

[0030] In this embodiment, the silicone ring serves as a seal to ensure a tight connection between the mounting tube 9 and the connecting tube 10, thereby preventing the foam ball from leaking from the connection during the transmission process. Secondly, the silicone ring has a certain elasticity and buffering effect, thereby reducing the vibration and impact generated by the mounting tube 9 and the connecting tube 10 during the connection process, thereby protecting the equipment and extending its service life.

[0031] In a further preferred embodiment of the utility model, a guide block 16 is fixedly installed on the top of the baffle 15, and the guide block 16 can extend into the discharge cylinder 17. The guide block 16 is hemispherical, and an electrostatic eliminator is provided on one side of the buffer box 4.

[0032] In this embodiment, the guide block 16 allows the foam balls to be discharged more smoothly through the discharge barrel 17 when the baffle 15 is opened. The hemispherical design of the guide block 16 can better guide the flow of the foam balls to ensure that the foam balls can accurately fall into the mold. Since the foam balls may generate static electricity during the transmission process, this may cause the foam balls to adsorb to each other or adhere to the buffer box 4, affecting normal discharge. The setting of the static eliminator can effectively eliminate the static electricity on the foam balls and prevent their adsorption or adhesion, thereby ensuring that the foam balls can smoothly enter the mold.

[0033] In a further preferred embodiment of the utility model, a one-way valve 18 is provided on the air inlet pipe of the vacuum pump 1 and the exhaust pipe of the fan 20, the suction head 8 is trumpet-shaped, the vacuum pump 1 can be installed on the wall at the top of the foam processing mold, and the material guide pipe 7 is a hose.

[0034] In this embodiment, the introduction of the one-way valve 18 ensures the one-way flow of the airflow in the pipeline and prevents the occurrence of airflow backflow or turbulence, which not only improves the stability of the airflow, but also helps to reduce energy consumption and noise, making the device run more efficiently and quietly. The trumpet shape can better gather and inhale the foam balls, improving the efficiency and accuracy of material suction. The trumpet-shaped design can also reduce the resistance of the airflow during the material suction process, allowing the foam balls to enter the device more smoothly. Compared with the hard tube, the hose has better flexibility and adjustability, and can bend and deform as needed to adapt to different positions and heights, thereby improving the scope of application and flexibility of the device.

[0035] In summary, compared with the related art, the present device can buffer and store a certain amount of foam ball raw materials by setting a buffer box 4, and the quantitative delivery of materials can be achieved by discharging the foam balls in the buffer box 4. The buffer box 4 is installed between the vacuum pump 1 and the material guide pipe 7 by setting the first threaded cylinder 2 and the second threaded cylinder 6, which makes it easier to replace buffer boxes 4 of different specifications. The fan 20 can increase the efficiency of foam ball discharge.
