Description

Technical Field

[0001] This utility model belongs to the field of synthetic resin molding technology, specifically relating to a particle regeneration device with adjustable cooling length. Background Technology

[0002] In synthetic resin molding plants, for the purpose of resource reuse, the recycled crushed material is fed into an extrusion molding machine for pellet regeneration processing. It is then mixed with unused resin material to achieve the purpose of resource reuse. Existing pellet regeneration equipment often has a fixed length for pellet cooling. In actual production, due to the differences in their thermophysical properties, different types of plastic pellets have different requirements for cooling rate and cooling length. If a device with a fixed cooling length is used, some pellets may not be cooled enough, affecting their subsequent processing performance, while other pellets may be over-cooled, resulting in energy waste and reduced production efficiency.

This device aims to solve the problem that the cooling length of the existing particle regeneration device is fixed and it is difficult to apply it to the regeneration of particles of different materials.

[0005] (2) Technical solution

[0006] To address the aforementioned technical problems, this utility model provides a particle regeneration device with adjustable cooling length. The device includes a frame, an injection molding assembly, a cutting assembly, and a touchscreen. The output end of the injection molding assembly is equipped with a first guide roller and a second guide roller. The second guide roller is connected to the frame via an X-axis adjustment assembly. The cutting assembly is mounted on the side of the frame via a Y-axis adjustment assembly. A resin rope from the output end of the injection molding assembly passes around the first and second guide rollers and is fed into the cutting assembly. The X-axis adjustment assembly is used to move the second guide roller and adjust the length of the resin rope between the injection molding assembly and the cutting assembly.

[0007] Preferably, the X-axis adjustment assembly includes an adjustment rod, an adjustment seat, and screws. The adjustment seat is fixedly connected to the right side of the frame. One end of the adjustment rod is inserted into the interior of the adjustment seat and fixedly connected by screws. The second guide roller is rotatably connected to the other end of the adjustment rod through a bearing.

[0008] Furthermore, the Y-axis adjustment assembly includes a U-shaped mounting base fixedly connected to the right side of the frame. A first motor is fixedly connected to the upper surface of the U-shaped mounting base. A movable plate is slidably arranged inside the U-shaped mounting base. A lead screw is fixedly connected to the output end of the first motor. The bottom end of the lead screw passes through the movable plate and is rotatably connected to the lower surface of the U-shaped mounting base through a bearing. The lead screw is threadedly connected to the movable plate. The cutting assembly is mounted on the movable plate.

[0009] Furthermore, a guide rod is fixedly connected to the inner top wall of the rear side of the U-shaped mounting base. The other end of the guide rod passes through the movable plate and is fixedly connected to the inner bottom wall of the U-shaped mounting base. The guide rod is slidably connected to the movable plate. A lifting sensor corresponding to the movable plate is fixedly connected to the outer surface of the bottom end of the guide rod.

[0010] Furthermore, a vertical plate is fixedly connected to the rear side of the upper surface of the movable plate, and a first tensioning roller is rotatably connected to the top left side of the vertical plate via a bearing. An installation rod is installed to the top right side of the vertical plate via bolts, and a second tensioning roller is rotatably connected to the other end of the installation rod via a bearing.

[0011] Furthermore, the cutting assembly includes a cutting box fixedly connected to the movable plate, a recycled particle outlet is provided at the bottom of the cutting box, a fixed blade is installed on the right side of the cutting box, a cutting motor is installed inside the cutting box, and a rotating blade corresponding to the fixed blade is installed at the output end of the cutting motor.

[0013] Furthermore, a bracket is fixedly connected to the right side of the upper surface of the mounting frame, and a guide roller motor is mounted on the bracket, with the first guide roller installed at the output end of the guide roller motor.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention involves plasticizing pulverized material through an injection molding assembly. A resin rope, fed from the nozzle, is guided by a first guide roller and then a second guide roller. The flow direction is adjusted by the first and second tension rollers, ensuring the resin rope enters the cutting assembly vertically. A fixed blade and a rotating blade work together to cut the resin rope to an adjustable length, allowing for natural cooling. This simplifies the complex cooling process of the resin rope, eliminating the need for a winding process and cooling water tanks. The required floor space is reduced to 1 / 2 to 1 / 3 of the previous method, saving space in factories and other locations and ensuring efficient use of available space. Furthermore, by incorporating X-axis and Y-axis adjustment components, when the cooling length needs adjustment, a first motor rotates a lead screw. During rotation, the lead screw moves a movable plate and the cutting assembly downwards, increasing the distance between the injection molding assembly and the cutting assembly. If the cooling length is insufficient, the length of the adjustment rod is adjusted to maximize the extension of the resin rope. The optimal cooling length can be easily set via a touchscreen, making it more suitable for the regeneration of particles from different materials, thus improving productivity and quality.

Detailed Implementation

[0022] This specific embodiment is a particle regeneration device with adjustable cooling length, and its structural schematic diagram is shown below. Figures 1-4 As shown, the device includes a frame 1, an injection molding assembly 2, a cutting assembly 3, and a touch screen 8. The output end of the injection molding assembly 2 is equipped with a first guide roller 4 and a second guide roller 5. The second guide roller 5 is connected to the frame 1 via an X-axis adjustment assembly 6, which can house the second guide roller 5. The frame 1 has space within it, allowing for horizontal extension and retraction. This allows the resin cord from the injection molding assembly 2 to be adjusted to the optimal length. The cutting assembly 3 is mounted on the side of the frame 1 via a Y-axis adjustment assembly 7, which allows the cutting assembly 3 to move up and down, thereby adjusting the optimal cutting temperature of the resin cord. The resin cord from the output end of the injection molding assembly 2 passes around the first guide roller 4 and the second guide roller 5 and is fed into the cutting assembly 3. The X-axis adjustment assembly 6 is used to move the second guide roller 5 and adjust the length of the resin cord between the injection molding assembly 2 and the cutting assembly 3.

[0023] like Figure 1 and Figure 2 As shown: In this embodiment, the X-axis adjustment assembly 6 includes an adjustment rod 601, an adjustment seat 602, and screws. The adjustment seat 602 is fixedly connected to the right side of the frame 1. One end of the adjustment rod 601 is inserted into the interior of the adjustment seat 602 and fixedly connected by screws. The second guide roller 5 is rotatably connected to the other end of the adjustment rod 601 through a bearing. By loosening the screws at the adjustment seat 602 and then adjusting the length of the adjustment rod 601, the position of the second guide roller 5 is adjusted. Finally, the screws at the adjustment seat 602 are tightened, thereby maximizing the extension of the resin rope and making up for the cooling time required by the resin rope.

[0024] like Figure 2 and Figure 3 As shown: In this embodiment, the Y-axis adjustment component 7 includes a U-shaped mounting base 701 fixedly connected to the right side of the frame 1. A first motor 702 is fixedly connected to the upper surface of the U-shaped mounting base 701. A movable plate 703 is slidably arranged inside the U-shaped mounting base 701. A lead screw 704 is fixedly connected to the output end of the first motor 702. The bottom end of the lead screw 704 passes through the movable plate 703 and is rotatably connected to the lower surface of the U-shaped mounting base 701 through a bearing. The lead screw 704 is threadedly connected to the movable plate 703. The cutting component 3 is mounted on the movable plate 703. When it is necessary to adjust the cooling length, the first motor 702 is started to drive the lead screw 704 to rotate. Since the lead screw 704 is threadedly connected to the movable plate 703, the lead screw 704 can drive the movable plate 703 and the cutting component 3 to move downward during the rotation, thereby increasing the distance between the injection molding component 2 and the cutting component 3 and making up for the cooling time required by the resin rope.

[0025] like Figure 3As shown: In this embodiment, a guide rod 709 is fixedly connected to the inner top wall of the rear side of the U-shaped mounting base 701. The other end of the guide rod 709 passes through the movable plate 703 and is fixedly connected to the inner bottom wall of the U-shaped mounting base 701. The guide rod 709 is slidably connected to the movable plate 703. A lifting sensor 710 corresponding to the movable plate 703 is fixedly connected to the outer surface of the bottom end of the guide rod 709. The guide rod 709 guides the movement of the movable plate 703 and the cutting assembly 3, preventing them from rotating with the lead screw 704, and making the up-and-down adjustment more stable.

[0026] like Figure 2 and Figure 4 As shown: In this embodiment, a vertical plate 705 is fixedly connected to the rear side of the upper surface of the movable plate 703. A first tensioning roller 706 is rotatably connected to the top left side of the vertical plate 705 via a bearing. A mounting rod 707 is bolted to the top right side of the vertical plate 705. A second tensioning roller 708 is rotatably connected to the other end of the mounting rod 707 via a bearing. Figure 4 In general, this refers to the setup used when regenerating resin granules, such as those that cure quickly or those with added special ingredients like glass fiber. The method of guiding the resin cord is similar to... Figure 1 They are the same, but very different. Figure 1 By adjusting the first guide roller 4 away from the nozzle 206, the cutting assembly 3 is used as close to the lower side as possible. In this case, although the first tension roller 706 and the second tension roller 708 are not located directly below the second guide roller 5, they can enter the cutting assembly 3 vertically.

[0027] In this embodiment, the cutting assembly 3 includes a cutting box 301 fixedly connected to the movable plate 703. The bottom end of the cutting box 301 is provided with a recycled particle outlet 302. A fixed blade 303 is installed on the right side of the cutting box 301. A cutting motor is installed inside the cutting box 301. A rotating blade 304 corresponding to the fixed blade 303 is installed at the output end of the cutting motor. The length of the particles is determined by the rotation speed of the rotating blade 304. The parameters of temperature, rotation speed, and height of the cutting assembly 3 can all be stored in the PLC inside the frame 1. The start-up conditions can be set through the touch screen 8. Anyone can use it immediately, so production can be completed simply.

[0028] In this embodiment, the injection molding assembly 2 includes a mounting frame 201, a barrel 202, a drive motor 203, a hopper 204, and a screw 205. The mounting frame 201 is fixedly connected to the left side of the upper surface of the frame 1. A nozzle 206 is installed at the right output end of the barrel 202, and a heater 207 is installed on the outer surface of the barrel 202. The diameter of the nozzle 206 when it is fed out is the same as the diameter of the recycled granules. The diameter of the nozzle 206 can be changed according to customer requirements. When it is fed out from the nozzle 206, the resin is in the form of a thin rope, hence it is called a resin rope.

[0029] In this embodiment, a bracket 9 is fixedly connected to the right side of the upper surface of the mounting bracket 201, and a guide roller motor 10 is mounted on the bracket 9. The first guide roller 4 is mounted on the output end of the guide roller motor 10.

[0030] Working principle: This device is used in general synthetic resin molding plants, etc., and is hung on a resin-specific crusher / pulverizer to process the crushed / pulverized resin material into particles, such as... Figure 1 and Figure 4 This demonstrates the adjustment device and the flow of resin filaments during the particle regeneration of crushed / pulverized materials such as polypropylene (PP), nylon (PA6), and polyethylene (PE), which typically require a certain curing time.

[0031] In use, firstly, crushed or pulverized resin material is added to the hopper 204. After the material is added to the hopper 204, it is supplied from the lower opening to the screw 205 located inside the barrel 202. Then, the drive motor 203 causes the crushed or pulverized resin material inside the screw 205 to be re-mixed and plasticized by the heater 207 located on the inner circumferential wall of the barrel 202 and the shear heat generated when the screw 205 rotates. The plasticized resin is then discharged through the nozzle 206 on the right side. The resin rope discharged from the nozzle 206 is guided in the order of the first guide roller 4 and the second guide roller 5, and then the flow direction is adjusted by the first tension roller 706 and the second tension roller 708 so that the resin rope enters the cutting assembly 3 vertically. The fixed blade 303 and the rotating blade 304 work together to cut the resin rope into an adjustable length. The cut recycled granules flow out from the recycled granule outlet 302. When the cooling length needs to be adjusted, the first motor 702 is started to drive the lead screw 704 to rotate. Since the lead screw 704 is threadedly connected to the movable plate 703, the lead screw 704 can drive the movable plate 703 and the cutting assembly 3 to move downward during the rotation, thereby increasing the distance between the injection molding assembly 2 and the cutting assembly 3. If the cooling length is still insufficient, the screw at the adjusting seat 602 is loosened, and then the length of the adjusting rod 601 is adjusted to adjust the position of the second guide roller 5. Finally, the screw at the adjusting seat 602 is tightened to maximize the extension of the resin rope and make up for the cooling time required for the resin rope.

[0032] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
