Description

Technical Field

[0001] This utility model relates to the field of plastic pellet production and processing technology, and in particular to a recycled plastic pellet granulator. Background Technology

[0002] The recycling of waste plastics is mainly accomplished through pelletizing equipment. Generally, the plastic is first put into a hot melt machine to melt it into a gel, then extruded through the hot melt machine, and then pulled into a water tank for cooling. After cooling, it is then pelletized by a pelletizing device to complete the production.

[0003] However, in existing equipment, when pulling the extruded gel-like plastic, workers need to first use auxiliary tools to gather multiple strips together and pull them through the guide rod in the water tank for cooling. When pulling the strips manually, it is difficult to control the pulling force evenly, which not only easily leads to deformation of the strips, but may also cause the strips to stick together and become impossible to separate and granulate.

[0004] Therefore, we propose a recycled plastic pelletizing machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a recycled plastic pelletizing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A recycled plastic pelletizing machine includes a hot melt extruder, a discharge die head, and a water tank. The discharge die head is installed at the extrusion end of the hot melt extruder, and the water tank is located below the discharge die head. A round rod is rotatably installed in the water tank near the end of the hot melt extruder, and a pair of guide rollers are also provided in the water tank for clamping the extruded plastic strip.

[0008] A side frame is provided on the same side of the guide roller. A movable block is movably installed in the hollow groove of the side frame. The lower guide roller is rotatably connected to the side frame, and the upper guide roller is rotatably connected to the movable block. A screw rod is vertically threaded through and screwed into the movable block.

[0009] A slide is mounted on the side frame via a hanger, and a lead screw is threaded through and connected to the slide. The lead screw is parallel to the length direction of the water tank and is rotatably connected to the water tank. One end of the lead screw is connected to a motor.

[0010] In a further embodiment, a plurality of guide rollers are uniformly fixed on the guide roller.

[0011] In a further embodiment, a guide rod parallel to the screw also slides through the interior of the movable block.

[0012] In a further embodiment, the screw is rotatably connected to the side frame, and the screw extends through the top of the side frame and is fitted with a handle.

[0013] In a further embodiment, a second motor is mounted on the side of the movable block, and the output end of the second motor is connected to the guide roller.

[0014] In a further embodiment, a straight rail is installed on the side wall of the water tank near the lead screw, and a slider matching the straight rail is installed on the side of the slide block.

[0015] In a further embodiment, a water tank is installed under the water tank via a support frame, and the water tank is connected to the head end of the water tank via a water pump and a pipe, and a slot is opened at the tail end of the water tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the rotating screw is set in this utility model, the distance between a pair of guide rollers can be adjusted to clamp the end of the extruded rubber strip. Then, the rotating screw drives the slide, hanger, side frame and a pair of guide rollers to move along the length of the water tank, so as to pull the rubber strip to cool inside the water tank. Compared with manual traction operation, it can not only control the traction force evenly and reduce the problem of deformation of the rubber strip when being pulled, but also prevent the rubber strips from sticking together, which facilitates the subsequent pelletizing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 A recycled plastic pelletizing machine includes a hot melt extruder 1, a discharge die 2, and a water tank 3. The discharge die 2 is installed at the extrusion end of the hot melt extruder 1, and the water tank 3 is located below the discharge die 2. The recycled plastic is melted by the hot melt extruder 1 and then limited by the discharge die 2, so that the molten plastic is extruded into multiple strips. The strips are introduced into the water tank 3, which is equipped with cooling water to cool and shape the strips. The cooled strips are then sent to a pelletizing device, where they are cut into plastic pellets. The pelletizing device is not shown in the figure.

[0027] Please see Figure 1-2Inside the water tank 3, a round rod 4 is rotatably mounted near the end of the hot melt extruder 1. The round rod 4 is submerged in cooling water, allowing the rubber strip to pass through the bottom of the round rod 4 first, making it easier to control the rubber strip so that it can be submerged in the cooling water. A pair of guide rollers 5 are also provided inside the water tank 3. The pair of guide rollers 5 are used to clamp the extruded plastic strip. A side frame 6 is provided on the same side of the guide rollers 5. One end of the hanger 7 is mounted on the side frame 6. The other end of the hanger 7 extends to the outside of the water tank 3 and is mounted on a slide block 8. A lead screw 9 is threaded through and connected to the slide block 8. The lead screw 9 is parallel to the length direction of the water tank 3, and both ends of the lead screw 9 are rotatably connected to the outer shell of the water tank 3 through bearing seats. One end of the lead screw 9 passes out of the bearing seat and is connected to a motor 10. When the motor 10 is working, it drives the lead screw 9 to rotate, and the slide block 8 moves along the lead screw 9. The guide roller 5 holding the rubber strip moves through the hanger 7 and the side frame 6, thus pulling the rubber strip.

[0028] For further details, please refer to Figure 3 Several guide rollers 51 are evenly fixed on the guide roller 5 to separate and clamp multiple rubber strips and prevent them from sticking together during the traction process.

[0029] Please see Figure 4 To improve the stability of the slide block 8 during movement, a straight rail 12 is installed on the side wall of the water tank 3 near the lead screw 9. The straight rail 12 is parallel to the lead screw 9, and a slider 11 matching the straight rail 12 is installed on the side of the slide block 8. The slider 11 slides on the straight rail 12, thereby limiting the slide block 8 and effectively preventing the slide block 8 from deflecting.

[0030] Please see Figure 3 To facilitate the adjustment of the guide roller 5 clamping the rubber strip, a movable block 61 is movably installed in the hollow groove inside the side frame 6. The lower guide roller 5 is rotatably connected to the side frame 6, and the upper guide roller 5 is rotatably connected to the movable block 61. At the same time, a screw 62 is vertically threaded through and screwed into the movable block 61. A guide rod 63 parallel to the screw 62 also slides through the interior of the movable block 61. The two ends of the screw 62 are rotatably connected to the side frame 6, and the screw 62 extends out of the top of the side frame 6 and is equipped with a handle. When the screw 62 rotates, the movable block 61 can be raised and lowered by the thread action and the limiting action of the guide rod 63, thereby driving the upper guide roller 5 to be raised and lowered for adjustment, making it easier to clamp or release the rubber strip.

[0031] For further details, please refer to Figure 3 A motor 2 13 is installed on the side of the movable block 61, and the output end of the motor 2 13 is connected to the guide roller 5. The motor 2 13 drives the guide roller 5 to rotate, which rubs against the rubber strip and can assist the rubber strip in transmission and movement.

[0032] Please see Figure 1-2To improve the cooling effect, a water tank 15 is installed under the water tank 3 via a support frame 14. The water tank 15 is connected to the head end of the water tank 3 via a water pump 16 and a pipe 17. One end of the pipe 17 is connected to the inside of the water tank 15, and the other end is connected to the inside of the water tank 3. A slot 31 is opened at the tail end of the water tank 3 to facilitate the overflow of cooling water from the slot 31, so that the cooling water in the water tank 3 and the water tank 15 can be recycled to ensure the cooling effect.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
