Description

Technical Field

[0001] This invention relates to the field of pelletizer technology, and specifically to a high-speed pelletizer for polymer materials. Background Technology

[0002] High-speed polymer pelletizers are core downstream equipment in extrusion granulation production lines. Their function is to cut molten polymers into uniformly sized standard plastic pellets. High-speed models can achieve cutting speeds of 15-60 m / s, suitable for medium- to high-capacity continuous production. They are divided into two main systems: cold cutting and die-face hot cutting. During production, the extruder die head extrudes multiple strips of material, which are then cooled and shaped in a water tank, dried by air knives, and then fed at a uniform speed by traction pressure rollers. High-speed rotating rollers cut cylindrical pellets, which are then collected.

[0003] After cutting, the shaped pellets fall into the collection bin at the bottom of the pelletizer and are collected by the collection box inside. After collection, the staff opens the box door on the side of the pelletizer, takes out the collection box, and collects the material inside.

[0004] When placing the collection bin, it is usually placed directly on the internal platform of the pelletizer cabinet. After the material is cut, it falls directly into it. However, during pelleting, the vibration of the equipment can easily cause the collection bin to move slightly, thus affecting subsequent collection. Alternatively, the collection bin can be fixed inside. However, when collecting the material later, the staff needs to reach into the inside of the pelletizer cabinet to touch the collection bin and then take out the particles inside, which is quite troublesome. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-speed pelletizer for polymer materials, which solves the problem mentioned in the background art of the inconvenience caused by improper placement of the collection box during material feeding and unloading.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A high-speed polymer pelletizer includes a pelletizer with a material chamber at its bottom and two hinged doors on the side of the material chamber. It also includes a receiving box, a hinged plate, a support assembly, a coordinating drive assembly, and a compression stabilizing assembly. The receiving box is positioned within the material chamber via a pull-sliding assembly. When material needs to be retrieved, the receiving box is pulled out via the pull-sliding assembly. The hinged plate is slidably mounted on the receiving box. Two support assemblies are provided, both positioned within the receiving box. After the receiving box is pulled out, the support assemblies provide support for the receiving box. Two coordinating drive assemblies are provided, both positioned on the hinged plate. When the hinged plate is pulled, the two support assemblies move synchronously. The compression stabilizing assembly is located on the side of each of the two door openings.

[0007] The receiving box has a collection chamber and two sliding chambers, with the two sliding chambers located on both sides of the collection chamber. The bottom of the collection chamber is open, and the opening and closing plate is slidably installed inside the collection chamber. The opening and closing plate can seal the collection chamber. After the particles are cut, the particles fall into the collection chamber for collection.

[0008] When the receiving box needs to be supported after it has been slid out of the material cavity, the support assembly further includes a sliding block, a damping shaft, a support column, and a support plate. The sliding blocks are slidably installed on both sides of the sliding cavity. The damping shaft is rotatably installed between the two sliding blocks. The support column is fixedly installed on the side of the damping shaft, and the support plate is fixedly installed at the bottom end of the support column.

[0009] When the opening and closing plate is pulled, it is necessary to simultaneously pull out the supporting column and the supporting plate. Furthermore, the coordinating drive component includes a coordinating rod and a coordinating frame. Each supporting column is fixedly installed with the coordinating rod. Two coordinating frames are rotatably installed on the top of the opening and closing plate. The bottom end of the coordinating rod is slidably installed on the bottom end of the receiving box. The side of the coordinating rod is provided with an abutment groove that can contact the side of the coordinating frame.

[0010] When the cavity door is closed and the opening and closing plate needs to be fixedly placed, the compression stabilizing assembly further includes a side block, a telescopic spring, and a compression block. The side block is fixedly installed on the side of the cavity door, and a groove is formed in the side block. One end of the telescopic spring is fixedly installed in the groove of the side block. The compression block is located in the groove of the side block, and the compression block is fixedly installed on the other end of the telescopic spring. A limit groove is formed on the inner side wall of the side block. A limit block is slidably installed in the limit groove, and the compression block is fixedly installed on the side of the limit block.

[0011] When the receiving box is pulled out of the material cavity, the pulling sliding assembly further includes a slide rail and a side slide bracket. There are two slide rails, both of which are fixedly installed inside the material cavity. Two side slide brackets are fixedly installed on both sides of the receiving box, and two side slide brackets are slidably installed on each slide rail. Two through slots are opened on the side of the receiving box, and the two through slots are respectively located at the same horizontal position as the side of the two cooperating brackets. After the two cavity doors are closed, the side of the two cavity doors are abutted against the two through slots.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a high-speed pelletizer for polymer materials, which has the following beneficial effects: In use, after the pelletizer finishes cutting the pellets, the pellets fall into the collection chamber of the receiving box. After collection, the chamber door is opened, and the receiving box can be pulled out of the chamber by the pulling component. Then, the operator pulls the opening and closing plate, and with the cooperation of the cooperating drive component, the supporting components on both sides slide synchronously. After the opening and closing plate is pulled out, the collection chamber of the receiving box is opened, and the pellets fall out. The operator can place a container below to receive the material. At the same time, the supporting components can support most of the moving discharge chamber of the receiving box. Therefore, the operator does not need to lift the receiving box by hand all the time when discharging the material, which is more convenient. After the material collection is completed, the opening and closing plate is pushed back to its original position to seal the bottom of the collection chamber. At the same time, the support column and support plate are placed into the sliding groove. Finally, the receiving box is pushed back to the original position of the material chamber for subsequent collection. Finally, the chamber door is closed, and the receiving box can be fixed by squeezing the stabilizing component. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example like Figure 1 , Figure 2 and Figure 5 As shown, a high-speed polymer material pelletizer includes a pelletizer 1 with a material cavity at its bottom. Two chamber doors 2 are hinged to the side of the material cavity. The pelletizer also includes a receiving box 3, an opening and closing plate 4, a support assembly, a coordinating drive assembly, and a compression stabilizing assembly. The receiving box 3 is installed in the material cavity via a pull-sliding assembly. When material needs to be retrieved, the receiving box 3 is pulled out by the pull-sliding assembly. The opening and closing plate 4 is slidably installed on the receiving box 3. Two support assemblies are provided, both of which are installed inside the receiving box 3. After the receiving box 3 is pulled out, it is supported by the support assemblies. Two coordinating drive assemblies are provided, both of which are installed on the opening and closing plate 4. When the opening and closing plate 4 is pulled to move, the two support assemblies are moved synchronously. Compression stabilizing assemblies are provided on the sides of both chamber doors 2.

[0017] During pelleting, the pelletizer 1 is first started to pelletize the material. Since the receiving box 3 has a collection chamber 5 and two sliding chambers 6, with the two sliding chambers 6 located on either side of the collection chamber 5, and the bottom of the collection chamber 5 is open, a sliding plate 4 is slidably installed inside the collection chamber 5. The sliding plate 4 can seal the collection chamber 5, allowing the pellets to fall completely into the collection chamber 5 of the receiving box 3. After collection, the chamber door 2 is opened. Figure 3 As shown, most of the receiving box 3 is slid out by pulling the sliding assembly. The pulling sliding assembly includes a slide rail 16 and a side slide bracket 17. There are two slide rails 16, both of which are fixedly installed in the material cavity. Two side slide brackets 17 are fixedly installed on both sides of the receiving box 3, and two side slide brackets 17 are slidably installed on each slide rail 16.

[0018] Specifically, the cavity door 2 is opened, and then the staff pulls out the receiving box 3, which drives the side slides 17 on both sides to move on the slide rail 16. This not only moves the receiving box 3 but also supports it. The process stops after most of the receiving box 3 has been pulled out.

[0019] like Figure 4 As shown, the pulled-out receiving box 3 is then supported by a support assembly, which includes a sliding block 7, a damping shaft 8, a support column 9, and a support plate 10. Sliding blocks 7 are slidably installed on both sides of the sliding cavity 6. The damping shaft 8 is rotatably installed between the two sliding blocks 7. The support column 9 is fixedly installed on the side of the damping shaft 8, and the support plate 10 is fixedly installed at the bottom of the support column 9. Specifically, after the receiving box 3 is pulled out, the worker takes a container and places it under the collection cavity 5 of the receiving box 3. Then, the worker pulls the two support plates 10 outwards at the same time. The support plates 10 drive the support column 9 to move synchronously. The support column 9 drives the sliding blocks 7 on both sides to move. The sliding blocks 7 are moved to the outermost end of the sliding cavity 6 and then stop. Then, the support column 9 is rotated to a vertical position by the damping shaft 8. At this time, the support plate 10 is in contact with the ground to provide support.

[0020] When moving, such as Figure 4As shown, the coordinating drive component can synchronously drive the opening and closing plate 4 to move outward, thereby opening the bottom end of the collection chamber 5 of the receiving box 3. At this time, the particles can fall down synchronously into the collection container below. The coordinating drive component includes a coordinating rod 11 and a coordinating frame 12. A coordinating rod 11 is fixedly installed on each support column 9. Two coordinating frames 12 are rotatably installed on the top of the opening and closing plate 4. Specifically, when pulled, the coordinating frame 12 rotates at the top of the opening and closing plate 4. Because the bottom end of the coordinating rod 11 is slidably installed on the bottom end of the receiving box 3, and the side of the coordinating rod 11 has an abutment groove that can contact the side of the coordinating frame 12, the side of the coordinating frame 12 can be rotated to contact the abutment groove, and then the support column 9 is pulled. When the pallet 10 is in operation, it can drive the cooperating rod 11 to slide synchronously on the receiving box 3, thereby driving the cooperating frame 12 to move outward. The cooperating frame 12 can drive the opening and closing plate 4 to slide out, thereby opening the bottom end of the collecting chamber 5 of the receiving box 3 and allowing the particles to fall out. The receiving box 3 has two through slots on its side, and the two through slots are respectively at the same horizontal position as the sides of the two cooperating frames 12. When the cooperating frame 12 contacts the side of the receiving box 3, it can pass through the through slots, so that the opening and closing plate 4 will not be hindered from sliding outward due to the obstruction of the side of the receiving box 3. Furthermore, when rotating the support column 9, the cooperating frame 12 can be rotated first so that it does not contact the abutment groove of the cooperating rod 11, thereby preventing the support column 9 from being obstructed from rotating.

[0021] After the material is collected, rotate the support column 9 to a horizontal position, then push the support column 9 and the opening and closing plate 4 into the receiving box 3, and then push the receiving box 3 into the feeding chamber. At this time, the internal components are fixed by the compression stabilizing component, such as... Figure 6 and Figure 7 As shown, the compression stabilizing assembly includes a side-mounted block 13, a telescopic spring 14, and a compression block 15. The side-mounted block 13 is fixedly installed on the side of the cavity 2, and a groove is formed inside the side-mounted block 13. One end of the telescopic spring 14 is fixedly installed in the groove of the side-mounted block 13. The compression block 15 is located in the groove of the side-mounted block 13, and the other end of the compression block 15 is fixedly installed. Specifically, after the cavity 2 is closed, because a limit groove is formed on the inner side wall of the side-mounted block 13, a limit block is slidably installed in the limit groove, and the compression block 15... When fixedly installed on the side of the limiting block, the two extrusion blocks 15 contact the two support plates 10 respectively. The support plates 10 exert an outward force on the extrusion blocks 15, and the extrusion blocks 15 compress the telescopic spring 14. At this time, the extrusion blocks 15 can slide in the side block 13 through the limiting block. At this time, the extrusion blocks 15 can press against the support plates 10 and fix them. And because the sides of the two chambers 2 are attached to the two through slots after the two chambers 2 are closed, the chambers 2 can be attached to the through slots during subsequent material feeding, and the particles will not fall out of the through slots.

[0022] Working principle: During pelletizing, the twin-screw extruder on the side of the pelletizer 1 first melts the polymer material into a cylindrical high-temperature plastic strip. After extrusion, conveying and cooling, the strip enters the pelletizer 1. Then, the high-speed rotating blades inside the pelletizer 1 cut the strip into several pellets. The pellets then fall into the collection chamber 5 of the receiving box 3. After cutting and collection are completed, the chamber door 2 is opened, and the operator pulls the receiving box 3 out, which drives the side slides 17 on both sides to move on the slide rails 16. Moving the receiving box 3 also provides support.

[0023] After pulling out the receiving box 3, the staff takes a container and places it under the collection chamber 5 of the receiving box 3. Then, the staff pulls the opening and closing plate 4 to move it outward. Before this, the cooperating frame 12 can be rotated to the abutment groove of the side contacting cooperating rod 11. When the opening and closing plate 4 slides outward, it can drive the two support plates 10 to move outward. The support plates 10 drive the support columns 9 to move synchronously. The support columns 9 drive the sliding blocks 7 on both sides to move. The sliding blocks 7 are moved to the sidemost end of the sliding chamber 6 and then stop. Then, the support columns 9 are rotated to the vertical position by the damping shaft 8. At this time, the support plates 10 are attached to the ground for support. At this time, the particles can fall directly into the collection container below. After collection, the opening and closing plate 4 and the receiving box 3 are pushed back to their original positions for subsequent collection. Finally, the chamber door 2 is closed.
