[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3. As an embodiment of this utility model, a feeding device for expandable polystyrene includes a housing 1. A support frame is installed at the bottom of the housing 1. A screening chamber 3 and a conveying chamber 4 are installed on the support frame. A crushing rod 2 is provided in the housing 1. A discharge pipe 5 is installed at the bottom of the housing 1. The end of the discharge pipe 5 away from the housing 1 is connected to the screening chamber 3. A sliding groove is opened on the side wall of the screening chamber 3. A slider 17 is slidably installed in the sliding groove. A screen plate 18 is provided on the slider 17.

[0023] The bottom of the screening chamber 3 is provided with a connecting pipe 6. The end of the connecting pipe 6 away from the screening chamber 3 is connected to the conveying chamber 4. The bottom of the conveying chamber 4 is provided with a feeding port 15. A conveying rod 13 is rotatably installed in the conveying chamber 4. A spiral blade 14 is installed on the conveying rod 13.

[0024] A drive assembly is installed on the housing 1, and the crushing rod 2 is connected to the drive assembly;

[0025] The screening chamber 3 is equipped with a transmission assembly, one end of which is connected to the drive assembly and the other end is connected to the slider 17.

[0026] A transmission mechanism is installed on the housing 1. One end of the transmission mechanism is connected to the drive assembly, and the other end is connected to the conveying rod 13.

[0027] In this embodiment, when the device is in use, a fixed amount of raw material is fed into the housing 1. The installed drive assembly drives the crushing rod 2 to rotate. The rotation of the crushing rod 2 crushes the agglomerated raw material, preventing the raw material from agglomerating and affecting its quality. At the same time, it prevents the agglomerated raw material from clogging the discharge pipe 5. Simultaneously, the drive assembly drives the transmission assembly and transmission mechanism to operate. The transmission assembly drives the slider 17 to slide back and forth, thus making the slider 17 drive the screen plate 18 to vibrate continuously. This allows the raw material falling into the screening chamber 3 to be screened. The qualified raw material falls to the bottom and falls into the conveying chamber 4 through the connecting pipe 6. The transmission mechanism drives the connected conveying rod 13 to rotate. The rotation of the conveying rod 13 drives the spiral blade 14 to rotate. The rotation of the spiral blade continuously conveys the raw material falling into the conveying chamber 4 to the feeding port 15, thereby allowing the screened raw material to continuously fall from the discharge port for feeding, improving the practicality of the device.

[0028] As an embodiment of the present invention, the drive assembly includes a dual-axis motor 8, which is mounted on the housing 1. The output end of the dual-axis motor 8 is equipped with a first drive shaft 7 and a second drive shaft 9. The first drive shaft 7 passes through the housing 1 and extends into the screening chamber 3. The crushing rod 2 is mounted on the first drive shaft 7 and rotates.

[0029] In this embodiment, the installed dual-axis motor 8 drives the first drive shaft 7 and the second drive shaft 9 connected to it to rotate. The first drive shaft 7 drives the crushing rod 2 connected to it to rotate. The rotation of the crushing rod 2 can crush the agglomerated raw materials and improve the quality of the raw materials for subsequent use. At the same time, the first drive shaft 7 drives the transmission component to operate. The transmission component drives the slider 17 to slide back and forth. In this way, the slider 17 drives the screen plate 18 to shake continuously, which can screen the raw materials falling into the screening chamber 3. The qualified raw materials fall to the bottom and fall into the conveying chamber 4 through the connecting pipe 6. The second drive shaft 9 drives the transmission mechanism to operate. The transmission mechanism drives the conveying rod 13 connected to it to rotate. The rotation of the conveying rod 13 drives the spiral blade 14 to rotate. The rotation of the spiral blade continuously conveys the raw materials falling into the conveying chamber 4 to the feeding port 15, so that the screened raw materials continuously fall from the feeding port for feeding, which improves the practicality of the device.

[0030] As an embodiment of the present utility model, the transmission assembly includes a driven shaft 19, which is rotatably connected to the side wall of the screening chamber 3. A cam 20 is installed on the driven shaft 19 and is disposed on one side of the slider 17. A connecting unit 16 is installed on the first drive shaft 7, and the end of the connecting unit 16 away from the first drive shaft 7 is connected to the driven shaft 19.

[0031] An elastic component 21 is provided in the chute. One end of the elastic component 21 is connected to the bottom wall of the chute, and the other end is connected to the slider 17.

[0032] In this embodiment, the rotation of the first drive shaft 7 drives the driven shaft 19 to rotate through the connecting unit 16. The rotation of the driven shaft 19 drives the cam 20 connected to it to rotate. The cam 20 rotates and intermittently contacts the slider 17. During the contact between the cam 20 and the slider 17, the slider 17 is driven to slide downward to compress the elastic component 21. The elastic component 21 is compressed and generates elastic force. When the cam 20 and the slider 17 are no longer in contact, the slider 17 is driven to reset under the elastic force of the elastic component 21. In this way, the slider 17 drives the screen plate 18 to shake continuously, which can screen the raw materials falling into the screening chamber 3. The qualified raw materials fall to the bottom and fall into the conveying chamber 4 through the connecting pipe 6.

[0033] As an embodiment of the present utility model, the transmission mechanism includes a transmission rod 11, which is rotatably connected to the housing 1. A connecting mechanism 10 is installed on the transmission rod 11, and the end of the connecting mechanism 10 away from the transmission rod 11 is connected to the second drive shaft 9.

[0034] A conveying unit 12 is installed on the transmission rod 11, and the end of the conveying unit 12 away from the transmission rod 11 is connected to the conveying rod 13.

[0035] In this embodiment, the rotation of the second drive shaft 9 drives the transmission rod 11 to rotate through the connecting mechanism 10. The rotation of the transmission rod 11 drives the transmission rod 13 to rotate under the action of the conveying unit 12. The rotation of the transmission rod 13 drives the spiral blade 14 connected to it to rotate. The rotation of the spiral blade continuously conveys the raw material falling into the conveying chamber 4 to the feeding port 15, thereby making the screened raw material continuously fall from the feeding port for feeding, improving the practicality of the device.

[0036] Furthermore, the connecting mechanism 10 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0037] Furthermore, the conveying unit 12 can be a gear set or a worm gear and worm wheel combination, which will not be described in detail here.

[0038] In one embodiment of this utility model, the elastic component 21 is a spring.

[0039] Furthermore, the elastic component 21 is a spring. When the spring is compressed, it generates elastic force. When the cam 20 and the slider 17 disengage, the spring drives the slider 17 to reset under the action of the elastic force.

[0040] The working principle of this utility model is as follows: When the device is in use, a fixed amount of raw material is fed into the housing 1. The installed dual-shaft motor 8 drives the first drive shaft 7 and the second drive shaft 9 connected to it to rotate. The first drive shaft 7 drives the crushing rod 2 connected to it to rotate. The rotation of the crushing rod 2 can crush the agglomerated raw material, improve the quality of the raw material for subsequent use, and at the same time prevent the agglomerated raw material from clogging the feed pipe 5. The rotation of the first drive shaft 7 drives the driven shaft 19 to rotate through the connecting unit 16. The rotation of the driven shaft 19 drives the cam 20 connected to it to rotate. The cam 20 rotates and intermittently contacts the slider 17. During the contact between the cam 20 and the slider 17, the slider 17 is driven to slide downward to compress the elastic component 21. The elastic component 21 is compressed and generates elastic force. When the slider 17 disengages from the slide, the elastic component 21 causes the slider 17 to reset, thus causing the slide 17 to continuously vibrate the screen plate 18, which can screen the raw materials falling into the screening chamber 3. The qualified raw materials fall to the bottom and into the conveying chamber 4 through the connecting pipe 6. The second drive shaft 9 rotates and drives the transmission rod 11 to rotate through the connecting mechanism 10. The rotation of the transmission rod 11 drives the conveying rod 13 to rotate under the action of the conveying unit 12. The rotation of the conveying rod 13 drives the spiral blade 14 connected to it to rotate. The rotation of the spiral blade continuously conveys the raw materials falling into the conveying chamber 4 to the feeding port 15, so that the screened raw materials continuously fall from the feeding port for feeding, improving the practicality of the device.
