[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the first embodiment of a screening device for extruded high-modification polystyrene foam materials provided by this utility model; Figure 2 for Figure 1 The diagram shows a side-bottom structural schematic. A screening device for extruded high-modification polystyrene foam material includes: a conveyor frame 1, a conveying mechanism 2 disposed on the surface of the conveyor frame 1, the conveying mechanism 2 including a conveyor belt 22, the conveyor belt 22 being movably connected to the surface of the conveyor frame 1;

[0030] The cutting mechanism 3 includes a cutting component 31, which is used to cut the foam board;

[0031] The blocking mechanism 5 includes a baffle 51, which is movably mounted on the surface of the conveyor frame 1.

[0032] The transmission mechanism 6 includes a push block 63, which is connected to the surface of the cutting component 31.

[0033] The conveying mechanism 2 conveys the foamed board. Two conveyor belts 22 are connected to the left and right ends of the conveyor frame 1 respectively, via a drive shaft. The motor housing drives the two support plates 21 to rotate synchronously, thus placing the foamed board on top of the conveyor belts 22. The belts can move the foamed board forward. The cutting mechanism 3 cuts the foamed board. The cutting component 31 can be a hot wire cutter, a rotary cutter, or an ultrasonic cutter, preferably an ultrasonic cutter. It uses high-frequency vibration of the cutter head to generate heat through friction between the foamed board material molecules, causing localized melting. Simultaneously, the mechanical force of the cutter head cuts the material, resulting in a smooth cut. An electric telescopic rod is connected to the top of the cutter head. The electric telescopic rod can drive the cutter head to move up and down. The function of the blocking mechanism 5 is to limit and block one end of the foaming plate and transmit signals to perform cutting work. A pressure sensor is installed on the surface of the baffle 51 and its top is located on the top of the support plate 21. When the foaming plate moves forward and connects with the baffle 51, the elastic element and strain gauge inside the pressure sensor deform, the resistance changes, and a signal is output to the controller. The function of the transmission mechanism 6 is to connect the transmission to realize the downward movement of the baffle 51. The push block 63 is fixedly connected to the surface of the electric telescopic rod cylinder in the cutting component 31, and one end of the surface is inclined. When the cutting component 31 moves, it can drive the push block 63 to move.

[0034] A support plate 21 is fixedly connected to the surface of the conveyor frame 1, and a sliding block 32 is connected to the top of the cutting component 31. A first driving component 33 is connected to the surface of the sliding block 32, and the first driving component 33 is used to drive the sliding block 32 to move.

[0035] There are two support plates 21, which are fixedly connected to the surface of the conveyor frame 1 at one end of the two conveyor belts 22 respectively. They can provide auxiliary support for the foam board and prevent the foam board from sinking in the middle. The first driving component 33 can be a transmission belt, a drive threaded rod, etc., preferably a transmission belt. The sliding block 32 is fixedly connected to the surface of the belt, and the top of the moving frame 42 is connected to a slide rail. The sliding block 32 is slidably connected to the surface of the slide rail. So when the belt in the first driving component 33 rotates, the sliding block 32 can drive the cutting component 31 to move left and right by limiting it through the slide rail.

[0036] The surface of the conveyor frame 1 is provided with a distance adjustment mechanism 4. The distance adjustment mechanism 4 includes a second driving component 41 and a moving frame 42. The second driving component 41 is used to drive the moving frame 42 to move. The moving frame 42 is used to support the cutting mechanism 3 and drive the cutting mechanism 3 to move.

[0037] The distance adjustment mechanism 4 is used to adjust the distance between the cutting component 31 and the baffle 51 to achieve the cutting of foam boards of different lengths. The second driving component 41 can be a hydraulic cylinder, a drive threaded rod, or a transmission belt, etc., preferably a drive threaded rod. The threaded rod in the second driving component 41 is rotatably connected to the surface of one end of the conveyor frame 1, and a slide rod is fixedly connected to the other end. A slider is fixedly connected to both ends of the bottom of the moving frame 42. The two sliders are threadedly connected to the surfaces of the threaded rod and the slide rod, respectively. When the motor drives the threaded rod to rotate, the moving frame 42 moves back and forth through the connection limit between the slide rod and one end of the moving frame 42.

[0038] The baffle 51 is connected to two ends with elastic members 52, which are used to push the baffle 51 to move and reset. The baffle 51 is connected to two ends with transmission members 61.

[0039] The elastic element 52 can be a spring slide rod or a spring telescopic rod, preferably a spring slide rod, and there are two of them. The two slide rods are fixedly connected to the two ends of the bottom of the conveyor frame 1, and the two ends of the baffle 51 are slidably connected to the surface of the two slide rods. One end of each of the two springs is fixedly connected to the two ends of the bottom of the baffle 51. In the natural state, the elastic force of the elastic element 52 pushes the baffle 51 to the top of the conveyor belt 22.

[0040] The transmission component 61 is used to drive the baffle 51 to move downward. The two ends of the moving frame 42 are movably connected to the transmission block 62. One end of the transmission component 61 is connected to the surface of the transmission block 62. The surface of the pushing block 63 is equipped with the pushing block 63.

[0041] There are two transmission components 61 and two transmission blocks 62. The two transmission blocks 62 are slidably connected to the left and right ends of the movable frame 42, and one of the transmission blocks 62 is L-shaped with one end being inclined. The transmission component 61 can be a telescopic rod or a sliding rod, preferably a sliding rod. One end of the two transmission components 61 is fixedly connected to the surface of the two transmission blocks 62, and slides through the left and right ends of the baffle 51. When the movable frame 42 moves, the transmission component 61 can slide inside the two ends of the baffle 51. When the pushing block 63 moves to the other end, the inclined end of the pushing block 63 connects with the inclined end of the transmission block 62, giving the transmission block 62 a downward push. The transmission component 61 then drives the baffle 51 to move downward through the transmission component 61.

[0042] The working principle of the screening device for extruded high-modification polystyrene foam materials provided by this utility model is as follows:

[0043] First, based on the length of the foam board, the second drive component 41 is activated, causing the moving frame 42 to drive the cutting mechanism 3 to move until the distance between the cutting component 31 and the baffle 51 is the length of the foam board. Then, the foam board is placed on the conveyor belt 22, and the conveyor belt 22 is driven by a motor to move the foam board. When one end of the foam board contacts the baffle 51, a signal is transmitted through a sensor to control the conveyor belt 22 to stop and the cutting component 31 and the first drive component 33 to start. The cutting component 31 then moves downwards, and the first drive component 33 drives the sliding block 3. 2. The cutting component 31 is moved to the other end to cut the foam board. When the cutting component 31 moves to the other end, the pushing block 63 is connected to the transmission block 62 and a downward pressure is applied to the transmission block 62. The transmission block 62 is then connected to the transmission component 61 to drive the baffle 51 to move downward. Then the conveyor belt 22 starts, and the cut foam board continues to move forward for conveying. Then the cutting component 31 is reset, and the pushing block 63 and the transmission block 62 are no longer connected. Under the elastic force of the elastic component 52, the baffle 51 moves upward to reset.

[0044] Compared with related technologies, the screening device for extruded high-modified polystyrene foam materials provided by this utility model has the following beneficial effects:

[0045] This utility model provides a screening device for extruded high-modification polystyrene foam materials. While conveying the foam board through the conveyor belt 22, the position of the cutting mechanism 3 can be adjusted simultaneously by the distance adjustment mechanism 4. When the foam board is connected to the surface of the baffle 51, the cutting component 31 can move to cut off the excess part of the foam board. The transmission mechanism 6 connects to the transmission, causing the baffle 51 to move downwards, so that the cut foam board continues to move forward. No external cutting equipment is required, which improves work efficiency.

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0048] Specifically, the second embodiment of this application provides a screening device for extruded high-modified polystyrene foam materials, which differs in that the surface of the cutting component 31 of the screening device for extruded high-modified polystyrene foam materials is provided with a waste cleaning mechanism 7. The waste cleaning mechanism 7 includes a push plate 71, which is movably installed on the surface of the cutting component 31. The outer surface of the push plate 71 is connected to a limit groove 72, and the surface of the push plate 71 is connected to a connecting rod 73.

[0049] The push plate 71 is slidably embedded in the top of the limiting groove 72, which is fixedly connected to the outer surface of the electric telescopic rod in the cutting component 31. One end of the connecting rod 73 is rotatably connected to the top of the cutter head in the cutting component 31, and the other end is rotatably connected to the top of the push plate 71. According to the lever principle, when the cutting component 31 moves upward, one end of the connecting rod 73 gives the push plate 71 a downward pushing force, and the bottom of the push plate 71 is connected to the top of the support plate 21.

[0050] The working principle of the screening device for extruded high-modification polystyrene foam materials provided by this utility model is as follows:

[0051] After the cutting component 31 finishes cutting the foam board, the cutting component 31 moves upward. During this process, the cutting component 31 drives one end of the connecting rod 73 to move upward and limits it through the connection between the push plate 71 and the limiting groove 72. The angle of the connecting rod 73 changes, and the other end pushes the push plate 71 downward, so that the push plate 71 moves downward and connects to the surface of the support plate 21. Then the first driving component 33 is activated, the sliding block 32 drives the cutting component 31 to move and reset, and the push plate 71 pushes the waste material on the top of the support plate 21 to one side.

[0052] Compared with related technologies, the screening device for extruded high-modified polystyrene foam materials provided by this utility model has the following beneficial effects:

[0053] This utility model provides a screening device for extruded high-modified polystyrene foam materials. The device uses a transmission push plate 71 to move downwards. When the sliding block 32 moves and resets, the push plate 71 can push the waste material to move, thereby cleaning the waste material at the top of the conveyor frame 1.
