Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to an extruder with a rejecting device. Background Art

[0002] Extruder is an important plastic machinery equipment.

[0029] The discharge assembly includes a telescopic drive part 12, an adapter plate 13, a transmission plate 14 and a push plate 15. A plurality of telescopic drive parts 12 are installed on the belt conveyor 2. The output end of the telescopic drive part 12 is connected to the adapter plate 13. A plurality of transmission plates 14 are installed on the adapter plate 13. The transmission plate 14 is connected to the push plate 15. The rotary drive part 10 is a motor, preferably a motor with a reducer, wherein the cutting blade 11 is oriented to be installed in a direction capable of cutting the raw material. The image recognition device 4 is a common device for image processing. The image recognition device 4 may be preferably one of the industrial cameras, which is electrically connected to a controller for controlling the movement of the belt conveyor 2 and the telescopic drive part 12. The controller is preferably a PLC or a computer. The telescopic drive part 6 and the telescopic drive part 12 are one of a cylinder, a hydraulic cylinder and an electric cylinder. The suction cup 7 is one of the linear modules, which may be a linear motor or a worm drive type module. The extruder body 1 is a common structure of an extruder, which is a twin-screw extruder and a single-screw extruder. One of the discharging machines has a structure in which a motor drives a screw for conveying raw materials to rotate, and the strip raw materials of the extruder are transmitted through a belt conveyor 2, and detected at an image recognition device 4. When raw materials with debris are detected, the telescopic drive part 6 drives the suction cup 7 to suck the transmitted raw materials, and the raw materials are lifted by the telescopic drive part 6, and then the positioning plate 9 drives the cutting blade 11 to rotate, and the moving module 8 drives the rotating drive part 10 and the cutting blade 11 to move, so that the cutting blade 11 cuts the transmitted raw materials, and the raw materials with debris detected on the raw materials are cut off and fall onto the belt conveyor 2.

[0030] Reference Figure 4 The discharging assembly also includes a support wheel 17 and a transmission belt 18. A plurality of support wheels 17 are rotatably connected to the belt conveyor 2.

The transmission belt 18 is a wide belt. The support wheel 17 and the transmission belt 18 are in a taut state, or the support wheel 17 is selected as a synchronous pulley, and the transmission belt 18 is a synchronous belt that matches the support wheel 17. Through the cooperation between the transmission belt 18 and the support wheel 17, the push plate 15 can be effectively guided, thereby improving the guiding effect of the push plate 15.

[0032] Reference Figure 6 The telescopic driving part 12 is installed inside the belt conveyor 2. The telescopic driving part 12 is installed at the interval between the rollers inside the belt conveyor 2. By installing the telescopic driving part 12 inside the belt conveyor 2, the protection effect of the telescopic driving part 12 can be improved and the damage to the belt conveyor 2 can be reduced.

The top plate 19 is connected to each supporting shaft 16. A plurality of image recognition devices 20 are installed on the top plate 19. A plurality of light shielding plates 21 for shading are connected to the top plate 19. The image recognition device 20 can emit light of a specific color to facilitate the detection of the transmitted raw materials in a relatively closed environment. The image recognition device 20 is electrically connected to a controller that controls the movement of the telescopic drive unit 12. The image recognition device 20 is preferably one of the industrial cameras. The image recognition device 20 is supported by the top plate 19. The image recognition device 20 detects the raw materials transmitted to the push plate 15, further determines the position of the raw materials, and avoids the malfunction of the telescopic drive unit 12.

[0034] When in use, the raw materials are conveyed via the belt conveyor 2, and the image recognition device 4 is started to detect the raw materials. When an area with debris is detected, the suction cup 7 is started, and the output shaft of the telescopic drive unit 6 is extended. The telescopic drive unit 6 drives the suction cup 7 to move to a position where the raw materials can be sucked. Then, the telescopic drive unit 6 drives the raw materials to rise to a height where the cutting blade 11 can cut. The rotary drive unit 10 is started, and the rotary drive unit 10 drives the cutting blade 11 to rotate. Then, the moving module 8 is started, and the moving module 8 drives the cutting part to cut the raw materials. After the cut area is transferred to the push plate 15 by the belt conveyor 2, the telescopic drive unit 12 drives the adapter plate 13, the transmission plate 14 and the push plate 15 to move, and the push plate 15 pushes the raw materials with debris to the outside of the belt conveyor 2.
