Description

Technical Field

[0001] This utility model discloses a water-cooling mechanism for producing plastic particles, specifically relating to the technical field of water-cooling mechanisms. Background Technology

[0002] The water-cooling mechanism for plastic pellet production refers to the device used to cool the molten plastic strips in the pelletizing machine during the stretching process.

[0003] Patent publication number CN207072114U discloses a water-cooling mechanism for plastic particle production. It includes a rectangular cooling water tank filled with cooling water. One end of the cooling water tank along its length is the inlet, located below the extruder outlet. The other end along the length of the cooling water tank is the outlet. A pressure frame is movably mounted on the top of the cooling water tank. Recessed grooves are provided on the top of both sides of the cooling water tank along its length. Rollers are located at the bottom of both ends of the pressure frame, and the rollers are supported and limited by the grooves. Several material distribution guide posts are provided at the bottom of the pressure frame on the extruder outlet side. A fixing pin is provided on the top of the cooling water tank at the inlet end, and a tension spring is mounted on the fixing pin, connected to the pressure frame. This design results in a reasonable structure and good cooling effect.

[0004] However, during use, the plastic strips that have just been melted and stretched from the granulator are at a very high temperature. When cooling in the water tank, the plastic strips need to pass under the first roller and slide on the upper surface of the other rollers. In this process, if the plastic strips are pulled manually, it is very easy to be burned by the plastic strips, which can cause safety accidents. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, during use, the plastic strips, which are hot-melted and stretched from the granulator, are at a very high temperature. When cooling them in a water tank, the plastic strips need to pass under the first roller and slide on the upper surfaces of the other rollers. This process of manually pulling the plastic strips can easily cause burns and safety accidents. Therefore, this invention proposes a water-cooling mechanism for plastic particle production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water-cooling mechanism for producing plastic particles, comprising a base, universal wheels installed on the bottom of the outer surface of the base, a bracket fixedly connected to the top of the outer surface of the base, a water tank fixedly connected to the top of the outer surface of the bracket, rollers rotatably connected to the inner wall of the water tank, a traction structure provided on the inner wall of the water tank, and an anti-adhesion structure provided on the top of the outer surface of the water tank. The traction structure includes a sliding groove, a first rectangular plate, and a round rod. A circular slider is slidably connected to the inner wall of the sliding groove, and a rectangular block is fixedly connected to one side of the outer surface of the circular slider. A first circular groove is formed on the top of the outer surface of the rectangular block.

[0007] The effect achieved by the above components is that, by setting up the chute and the circular slider, the traction structure can pull the plastic strip from one side of the water tank to a suitable position on the other side.

[0008] Preferably, the first rectangular plate is fixedly connected to the bottom of the inner wall of the water tank, and a second circular groove is formed on the top of the outer surface of the first rectangular plate.

[0009] The effect achieved by the above components is that by setting the first rectangular plate and the second circular groove, the plastic strip can have a limiting effect on the first roller.

[0010] Preferably, a positioning plate is fixedly connected to the top of the outer surface of the round rod, a threaded rod is threadedly connected to the outer surface of the positioning plate, and a handle is fixedly connected to the top of the outer surface of the threaded rod.

[0011] The effect achieved by the above components is that by setting the threaded rod, the position of the pressure plate can be adjusted up and down, thereby enabling the traction structure to better traction the plastic strip.

[0012] Preferably, a pressure plate is rotatably connected to the bottom of the inner wall of the threaded rod, and a rubber pad is fixedly connected to the bottom of the outer surface of the pressure plate.

[0013] The effect achieved by the above components is that by setting up the pressure plate and rubber pad, in conjunction with the first circular groove, the traction of the plastic strip is made more stable.

[0014] Preferably, a fixing groove is formed on one side of the outer surface of the circular slider, and a fixing hole is formed on one side of the outer surface of the water tank. A first buckle is inserted and connected to the inner wall of the fixing hole, and the size and shape of the outer surface area of ​​the first buckle are adapted to the size and shape of the inner wall surface area of ​​the fixing groove.

[0015] The effect achieved by the above components is that by setting the first buckle, the round slider can be fixed to the water tank, thereby ensuring the traction effect and facilitating the docking of the plastic strip with the pelletizer.

[0016] Preferably, the anti-adhesion structure includes limiting plates, which are symmetrically and fixedly connected to the top of the outer surface of the water tank. The inner walls of the two limiting plates are rotatably connected to rotating rods, and a second rectangular plate is fixedly connected to one side of the outer surface of the rotating rods. A third circular groove is formed on the top of the outer surface of the second rectangular plate.

[0017] The effect achieved by the above components is as follows: by setting the second rectangular plate and the third circular groove, the freshly extruded plastic strips can have a limiting effect, avoiding the plastic strips from sticking together, which would prevent normal pelletizing or excessive pellet volume during subsequent pelletizing. The rotating rod can guide the plastic strips and connect them with the second circular groove on the first rectangular plate, assisting in the use of the traction structure.

[0018] Preferably, a circular plate is fixedly connected to one side of the outer surface of the rotating rod, a limiting hole is opened on one side of the outer surface of the circular plate, a second buckle is inserted and connected to the inner wall of the limiting hole, and a limiting groove is opened on one side of the outer surface of the limiting plate, the size and shape of the inner wall surface area of ​​the limiting groove are adapted to the size and shape of the outer surface area of ​​the second buckle.

[0019] The effect achieved by the above components is that by setting the second buckle, the rotating rod can be limited, thereby ensuring the stability of the second rectangular plate.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. By using the traction structure, the plastic strips that have just been melted and stretched from the granulator are kept at a very high temperature. When cooling in the water tank, the plastic strips need to pass under the first roller and slide on the upper surface of the other rollers. During this process, the plastic strips are manually pulled, which can easily cause burns and safety accidents.

[0022] 2. The anti-adhesion structure provides a limiting effect for the freshly extruded plastic strips, preventing them from sticking together and hindering proper pelletizing or resulting in excessively large pellets. The rotating rod guides the plastic strips, aligning them with the second circular groove on the first rectangular plate, thus aiding the use of the traction structure. Attached Figure Description

[0029] Reference Figure 1-4 As shown, this utility model provides a technical solution: a water-cooling mechanism for producing plastic particles, including a base 1, a caster wheel 2 installed on the bottom of the outer surface of the base 1, a bracket 3 fixedly connected to the top of the outer surface of the base 1, a water tank 4 fixedly connected to the top of the outer surface of the bracket 3, a roller 5 rotatably connected to the inner wall of the water tank 4, a traction structure 6 provided on the inner wall of the water tank 4, and an anti-sticking structure 7 provided on the top of the outer surface of the water tank 4.

[0030] The specific design and function of its traction structure 6 and anti-adhesion structure 7 will be explained below.

[0031] Example 1: Refer to Figure 2 , Figure 3As shown in this embodiment: the traction structure 6 includes a slide 601, a first rectangular plate 605, and a round rod 607. A round slider 602 is slidably connected to the inner wall of the slide 601. A rectangular block 603 is fixedly connected to one side of the outer surface of the round slider 602. A first circular groove 604 is formed on the top of the outer surface of the rectangular block 603. By setting the slide 601 and the round slider 602, the traction structure 6 can pull the plastic strip from one side of the water tank 4 to a suitable position on the other side. The first rectangular plate 605 is fixedly connected to the bottom of the inner wall of the water tank 4. A second circular groove 606 is formed on the top of the outer surface of the first rectangular plate 605. By setting the first rectangular plate 605 and the second circular groove 606, the plastic strip can have a limiting effect on the first roller 5. A positioning plate 608 is fixedly connected to the top of the outer surface of the round rod 607. A threaded rod 609 is threadedly connected to the outer surface of the positioning plate 608. A handle 610 is fixedly connected. By setting a threaded rod 609, the position of the pressure plate 611 can be adjusted up and down, thereby enabling the traction structure 6 to better traction the plastic strip. The pressure plate 611 is rotatably connected to the bottom of the inner wall of the threaded rod 609. A rubber pad 612 is fixedly connected to the bottom of the outer surface of the pressure plate 611. By setting the pressure plate 611 and the rubber pad 612, in conjunction with the first circular groove 604, the traction of the plastic strip is made more stable. A fixing groove 613 is opened on one side of the outer surface of the circular slider 602, and a fixing hole 614 is opened on one side of the outer surface of the water tank 4. A first buckle 615 is inserted and connected to the inner wall of the fixing hole 614. The size and shape of the outer surface area of ​​the first buckle 615 are adapted to the size and shape of the inner wall surface area of ​​the fixing groove 613. By setting the first buckle 615, the circular slider 602 can be fixed to the water tank 4, thereby ensuring the traction effect and facilitating the docking of the plastic strip with the pelletizer.

[0032] Example 2: Refer to Figure 4As shown in this embodiment: the anti-adhesion structure 7 includes limiting plates 701, which are symmetrically fixedly connected to the top of the outer surface of the water tank 4. A rotating rod 702 is rotatably connected to the inner walls of the two limiting plates 701. A second rectangular plate 704 is fixedly connected to one side of the outer surface of the rotating rod 702. A third circular groove 705 is provided on the top of the outer surface of the second rectangular plate 704. By setting the second rectangular plate 704 and the third circular groove 705, the freshly extruded plastic strips can have a limiting effect, preventing the plastic strips from sticking together and causing them to be unable to be granulated normally or to have excessively large granulation volume during subsequent granulation. The rotating rod 702 can... A plastic strip is used for drainage and is connected to the second circular groove 606 on the first rectangular plate 605 to assist in the use of the traction structure 6. A circular plate 706 is fixedly connected to one side of the outer surface of the rotating rod 702. A limiting hole 707 is opened on one side of the outer surface of the circular plate 706. A second buckle 708 is inserted and connected to the inner wall of the limiting hole 707. A limiting groove 709 is opened on one side of the outer surface of the limiting plate 701. The size and shape of the inner wall surface area of ​​the limiting groove 709 are adapted to the size and shape of the outer surface area of ​​the second buckle 708. By setting the second buckle 708, the rotating rod 702 can be limited, thereby ensuring the stability of the second rectangular plate 704.

[0033] Working principle: In use, first use the casters 2 to move the base 1 along with the plastic particle production water-cooling mechanism to a suitable position. Inject an appropriate amount of softened water into the water tank 4. Use the circular plate 706 to rotate the rotating rod 702, rotating the second rectangular plate 704 to the point where the plastic strip is extruded in the granulator. The plastic strip flows into the third circular groove 705. Again, use the circular plate 706 to rotate the second rectangular plate 704, bringing it close to the first rectangular plate 605. Then, pass the second buckle 708 through the limiting hole 707 and fix it in the limiting groove 709. At this time, the plastic strip slides into the second circular groove 606 on the surface of the first rectangular plate 605 in the third circular groove 705, and passes through... On the water surface, after initial cooling, when the plastic strip slides into the first circular groove 604, the threaded rod 609 is rotated using the handle 610 to rotate the pressure plate 611 downwards, pressing the rubber pad 612 tightly against the plastic strip. At this time, the handle 610 is held and pulled, causing the pressure plate 611 and the rectangular block 603 to pull the plastic strip. With the cooperation of the sliding groove 601 and the circular slider 602, the plastic strip is pulled and slid. At this time, the plastic strip that is subsequently extruded will pass under the first roller 5 and slide on the upper surface of the subsequent roller 5. When it slides to the alignment of the fixing groove 613 and the fixing hole 614, the two are fixed by the first buckle 615. At this time, the plastic strip has completed cooling.
