Description

Technical Field

[0001] This utility model relates to the technical field of anti-blocking material mechanisms, and in particular to an anti-blocking material mechanism for a tracked pelletizing equipment. Background Technology

[0002] In plastic extrusion production lines, the tracked traction device provides stable traction through the friction between the track and the material, ensuring that the material is stretched evenly and continuously during extrusion. This device has good material adaptability and high production capacity. After extruding plastic strips, the tracked pelletizing equipment needs to be cooled and transported to the pelletizing mechanism via a tracked conveyor for pelletizing. However, during the conveyor's transport, the plastic strips are prone to rolling or displacement due to vibrations from the tracked conveyor and cooling airflow from the fan, causing them to fail to align properly into the pelletizing slots and resulting in blockages in the output of the plastic strips from the tracked conveyor. Utility Model Content

[0003] In response to the technical problem in existing patents that the device is prone to rolling or displacement due to vibration of the tracked conveyor and cooling air blowing of the fan during use, resulting in failure to properly align and enter the pelletizing slot, and causing obstruction and blockage of the plastic strip output on the tracked conveyor, this utility model provides an anti-blocking material mechanism for a tracked pelletizing device.

[0004] The technical solution adopted by this utility model is: an anti-clogging mechanism for a tracked pelletizing device, comprising: a tracked conveyor, a discharge plate disposed on one side of the tracked conveyor, and a guide conveying mechanism disposed on the upper side of the tracked conveyor. The guide conveying mechanism includes a U-shaped frame fixed on the tracked conveyor, multiple guide conveying components disposed within the U-shaped frame, a first drive mechanism and a second drive mechanism disposed on one side of the U-shaped frame. The guide conveying components include two support plates slidably fitted within the U-shaped frame, a bidirectional threaded rod rotatably fitted within the U-shaped frame and threadedly fitted with the two support plates, and two guide conveying wheels rotatably fitted on opposite inner sides of the two support plates. The multiple bidirectional threaded rods are fixedly sleeved on the output end of the first drive mechanism, and the multiple guide conveying wheels are slidably sleeved on the output end of the second drive mechanism.

[0005] Furthermore, the top surface of the inner wall of the U-shaped frame is provided with a T-shaped channel, and the upper end of the support plate is a T-shaped plate structure, with the upper end of the support plate slidingly fitted in the T-shaped channel.

[0006] Furthermore, the first drive mechanism includes a first servo motor fixed to one side of the U-shaped frame, a transmission rod located at one end of the output shaft of the first servo motor extending into the T-shaped channel, the bidirectional threaded rod being fixedly sleeved on the transmission rod, the two ends of the bidirectional threaded rod having opposite thread directions, and the two ends of the bidirectional threaded rod respectively engaging with the two support plates in the guide conveying assembly.

[0007] Furthermore, a bearing is installed through one side of the support plate, the guide conveyor wheel has a frustum-shaped structure, and a protrusion is provided at one end of the guide conveyor wheel, the protrusion being fixed inside the bearing.

[0008] Furthermore, one end of the guide conveyor wheel is provided with a polygonal hole that passes through the protrusion. The second drive mechanism includes a second servo motor fixed on one side of the U-shaped frame and a polygonal transmission column located at the output end of the second servo motor. The guide conveyor wheel and the protrusion are slidably sleeved on the polygonal transmission column through the polygonal hole.

[0009] Furthermore, a guide strip is provided on one side of the support plate, one end of which extends into the discharge plate. A discharge port is provided on one side of the track conveyor, one end of which is fixed in the discharge port. The end of which extends out of the discharge port is a U-shaped plate structure. A water spraying device and multiple fan cooling devices are provided on the upper side of the track conveyor.

[0010] The beneficial effects of this utility model are:

[0011] By activating the first servo motor to drive the transmission rod, multiple bidirectional threaded rods are rotated. The bidirectional threaded rods drive two support plates inside the guide conveying assembly, and the plastic strip is guided and conveyed by two guide conveying wheels.

[0012] The second servo motor drives the polygonal transmission column to rotate, which in turn drives multiple sliding guide conveyor wheels to rotate synchronously. This makes it easier to adapt to the clamping and guiding of plastic strips of different sizes, increasing the probability that the plastic strips are aligned and enter the pelletizing knife groove, and reducing the probability that the plastic strips are blocked and cause blockage.

[0013] By guiding the plastic strip through the two adjacent guide strips on the discharge plate, the probability of the plastic strip being aligned with the pelletizing knife groove is further increased, and the probability of the plastic strip being blocked is reduced. By improving the alignment accuracy in the input knife groove, the pelletizing effect of the plastic strip is improved. Attached Figure Description

[0027] Furthermore, a bearing 306 is installed through one side of the support plate 3021, and the guide conveyor wheel 3023 has a frustum-shaped structure, which facilitates the two guide conveyor wheels 3023 to cooperate with the track on the crawler conveyor 1 to form a three-point positioning, adapting to the stable conveying of rubber strips of different shapes. One end of the guide conveyor wheel 3023 is provided with a protrusion 3024, which is fixed in the bearing 306.

[0028] Furthermore, one end of the guide conveyor wheel 3023 is provided with a polygonal hole 3025 that passes through the protrusion 3024.
