Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism of a pelletizing device. Background Art

[0002] At present, a common method of plastic granulation is to use an extruder to mix and plasticize the granulator material to form a plastic melt, and then extrude plastic strips from the extruder die head. After the plastic strips are cooled in a cooling water trough filled with cooling water, the plastic pelletizer cuts the plastic strips into plastic pellets of a certain length.

[0003] Existing plastic pelletizers can basically realize automatic pelletizing, and the materials after pelletizing are generally discharged through the corresponding discharge plates. In order to prevent the material from falling, it is necessary to add baffles on both sides of the discharge plate, and in order to prevent the material from piling up and clogging, which leads to the problem that the material cannot be discharged in time, many manufacturers have also set up baffles and further added power mechanisms to make the discharge plate swing or shake during discharge, thereby increasing the kinetic energy and allowing the material to be discharged smoothly. However, such a setting results in different tooth sizes of plastic particles after cutting, and particles of different sizes enter the same collection box during discharge, requiring secondary screening. To this end, we propose a discharge mechanism for a pelletizing device, so that the plastic particles can be directly screened and discharged during discharge to avoid secondary screening. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a material discharge mechanism of a pelletizing device.

[0005] The technical solution adopted by the utility model to solve its technical problems is a feeding mechanism of a pelletizing device, comprising a bottom plate and a support plate, a collecting mechanism is installed at the plate wall of the support plate, the collecting mechanism is composed of a frame, a screening plate, honeycomb holes A, honeycomb holes B and a feeding pipe combination, a group of screening plates are installed at the inner wall of the frame by bolts, honeycomb holes A are opened at half of the plate wall of the screening plate, and honeycomb holes B are opened at the other half of the plate wall of the screening plate, the honeycomb holes A and the honeycomb holes B are different in size, a group of symmetrical feeding pipes are connected and welded at the bottom of the frame, and a group of the feeding pipes are welded to the pipe wall of the support plate.

[0006] By adopting the above technical scheme, when the plastic particles are screened and discharged, since a collection mechanism is installed at the plate wall of the support plate, the collection mechanism is composed of a frame, a screening plate, honeycomb hole A, honeycomb hole B and a discharge pipe. When the plastic particles fall into the frame, since a screening plate is installed in the frame by bolts, honeycomb hole A is opened at one half of the plate wall of the screening plate, and honeycomb hole B is opened at the other half of the plate wall of the screening plate. The sizes of honeycomb hole A and honeycomb hole B are different. The frame is then driven to swing left and right by a swing mechanism, so that the plastic particles move at the screening plate, so that plastic particles of different sizes enter the discharge pipe through the honeycomb hole A and the honeycomb hole B respectively, so as to realize the screening of the plastic particles when discharging, avoid secondary screening, and improve efficiency.

[0007] Specifically, it also includes a swing mechanism, and the swing mechanism is installed at the top of the bottom plate.

[0008] By adopting the above technical solution, the frame can be driven to swing left and right through the swing mechanism.

[0009] Specifically, the swing mechanism is composed of a bracket, a fixed plate, a toothed rod, a disc, a vertical plate, a motor, a vertical slot frame, a limit rod and an arc toothed plate. A motor is installed at the top of the base plate through the bracket, and a disk is installed at the output end of the motor. A limit rod is welded at the wall of the disk, and the limit rod passes through the vertical slot of the vertical slot frame. A vertical plate is welded at the top of the base plate, and the wall of the vertical plate is rotatably connected to the vertical slot frame through an anchor rod. An arc toothed plate is welded at one end of the vertical slot frame, and a group of symmetrical fixed plates are welded at the top of the base plate. A toothed rod is plugged into the fixed plates of the group, and the teeth of the toothed rod are meshed with the teeth of the arc toothed plate.

[0010] By adopting the above technical scheme, when the frame is swung, a swing mechanism is installed at the top of the bottom plate, and the swing mechanism is composed of a bracket, a fixed plate, a toothed rod, a disc, a vertical plate, a motor, a vertical slot frame, a limit rod and an arc toothed plate. The disc is driven by the motor to rotate, and the limit rod is welded at the disc wall of the disc, and the limit rod passes through the vertical slot at the vertical slot frame. Since the vertical plate is rotatably connected with the vertical slot frame by the anchor rod at the plate wall, the vertical slot frame is rotationally limited by the anchor rod, and since the vertical slot frame has a single arc toothed plate welded thereon, the teeth of the arc toothed plate are meshed with the teeth of the toothed rod, and the toothed rod passes through the fixed plate, and the toothed rod is limited by the fixed plate, so that the arc toothed plate drives the toothed rod to move left and right at the plate wall of the fixed plate, so that the toothed rod drives the support plate to move, thereby realizing the left and right movement of the frame.

[0011] Specifically, a group of symmetrical support plates are welded to the rod wall of the toothed rod.

[0012] By adopting the above technical solution, it is convenient to fix the support plate.

[0013] Specifically, a movable pulley is installed at the bottom of the base plate.

[0014] By adopting the above technical solution, the bottom plate can be conveniently moved through the pulley.

The sizes of honeycomb holes A and honeycomb holes B are different. Then, the frame is driven to swing left and right by a swinging mechanism, so that the plastic particles move at the screening plate, so that plastic particles of different sizes enter the feeding pipe through the honeycomb holes A and the honeycomb holes B respectively, so as to realize the screening of the plastic particles during feeding, avoid secondary screening, and improve efficiency.

The circular plate is driven by a motor to rotate, and a limit rod is welded on the wall of the circular plate, and the limit rod passes through the vertical slot of the vertical slot frame. Since the vertical plate is rotatably connected to the vertical slot frame by an anchor rod at the wall of the vertical plate, the vertical slot frame is rotationally limited by the anchor rod. Since the vertical slot frame has a single arc toothed plate welded thereon, the teeth of the arc toothed plate are meshed with the teeth of the toothed rod, and the toothed rod passes through the fixed plate, and the toothed rod is limited by the fixed plate, so that the circular arc toothed plate drives the toothed rod to move left and right at the wall of the fixed plate, so that the toothed rod drives the support plate to move, thereby realizing the left and right movement of the frame.
