Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion equipment technology, and more specifically, to a precision extrusion molding equipment for plastic products. Background Technology
[0002] An extruder is an important piece of plastic machinery, and most plastic products can be produced and manufactured through extrusion molding. The extruder motor is a crucial component of the extruder, serving as its prime mover and providing the large thrust required by the extruder screw.
[0003] Existing extrusion equipment adds plastic granules into the equipment through the feeding port during operation. However, since the feeding port of the existing equipment does not have a screening device, larger diameter impurities will be separated during actual use. Small impurities will be mixed into the plastic granules. These impurities are small in size and not easy to detect. They will affect the overall product quality during subsequent processing. Utility Model Content

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.
[0006] A precision extrusion molding equipment for plastic products includes an extrusion equipment body. A screening hopper is provided on the top of the extrusion equipment body. A plurality of first screening components and second screening components are respectively arranged on both sides of the interior of the screening hopper. The plurality of first screening components and second screening components are arranged alternately, and the ends of the first screening components and second screening components that are far apart from each other are respectively connected to the inner side of the screening hopper. The ends of the first screening components and second screening components that are close to each other are lower than their other ends. A first opening is formed between one end of the first screening component and the screening hopper, and a second opening is formed between one end of the second screening component and the screening hopper. The first screening component includes a screening screen and a collection frame. The screening screen is snapped and fixed to the top of the collection frame. The second screening component has the same structure as the first screening component.
[0007] Preferably, the side of the collection frame is provided with a discharge port, and a sealing part is installed on the discharge port to perform a sealing function, and the plurality of discharge ports are located on the same plane.
[0008] Preferably, the screening hopper has an opening on one side, and the projections of the plurality of discharge ports on the plane of the opening are all within the area enclosed by the opening, and a sealing door is hinged at the opening.

[0010] Preferably, one end of the first screening component and the second screening component are respectively connected to a limiting component. The limiting component includes a support plate and a threaded rod. The support plate is fixed to one end of the first screening component or the second screening component.

[0013] Compared with the prior art, the advantages of the present invention are:
[0014] I. This solution uses alternating screens to screen plastic granules. Smaller impurities will fall through the mesh of the screen into the bottom of the collection frame, thus separating the plastic granules from the impurities. The impurities will be collected in the collection frame, while the plastic granules will roll down the screen into the extrusion equipment body. The alternating arrangement of the first and second screening components can prolong the movement time of the plastic granules inside the screening hopper, increase the contact time with the screen, and ensure the screening effect. Separating impurities from the plastic body can improve the quality of the product produced by the extrusion equipment body during operation. This application achieves the separation of plastic granules and impurities by gravity, without the need for additional power, saving energy and reducing costs. Attached Figure Description

[0023] Example 1:
[0024] Please see Figure 1-6 A precision extrusion molding equipment for plastic products includes an extrusion equipment body 1, which is an extruder. A screening hopper 2 is installed on the top of the extrusion equipment body 1. The upper cross-section of the screening hopper 2 is larger than its lower cross-section. Both the upper and lower cross-sections of the screening hopper 2 are rectangular, facilitating the subsequent installation of a first screening section 3 and a second screening section 4. It also allows the user to easily add plastic granules into the screening hopper 2. Several connecting members 13 are alternately arranged on both sides inside the screening hopper 2. Each connecting member 13 includes a fixing frame 14 and a rotating... The rotating frame 15, fixed frame 14, and screening hopper 2 are fixedly connected. The other end of the fixed frame 14 is an arc-shaped notch, and one end of the rotating frame 15 is an arc-shaped protrusion that matches it. The fixed frame 14 and the rotating frame 15 rotate in cooperation. The cooperation between the arc-shaped notch and the protrusions can prevent gaps from forming when the rotating frame 15 rotates around the fixed frame 14, thus preventing the risk of plastic particles leaking out through the gap between the rotating frame 15 and the fixed frame 14. At the same time, it can prevent plastic particles from getting stuck in the gap between the fixed frame 14 and the rotating frame 15, ensuring smooth rotation.
[0025] One end of the rotating frame 15 located inside the screening hopper 2 is fixedly connected to a first screening component 3, and one end of the rotating frame 15 located on the other side is connected to a second screening component 4. The first screening component 3 and the second screening component 4 have the same structure. A first opening 5 is formed between the end of the first screening component 3 away from the corresponding connecting member 13 and the screening hopper 2. The end of the first screening component 3 near the connecting member 13 is higher than the end near the first opening 5. A second opening 6 is formed between the end of the second screening component 4 away from the corresponding connecting member 13 and the screening hopper 2. The end of the second screening component 4 near the connecting member 13 is higher than the end near the second opening 6. The first screening component 3 and the second screening component 4 can continuously screen plastic particles. The plastic particles are screened, and the alternating inclined arrangement of the first screening component 3 and the second screening component 4 can extend the movement path of the plastic particles inside the screening hopper 2, ensuring the separation effect between impurities and plastic particles. At the same time, the first screening component 3 and the second screening component 4 are connected to the screening hopper 2 through a rotatable connector 13, which can adjust the tilt angle of the first screening component 3 and the second screening component 4, that is, control the movement speed of the plastic particles on the first screening component 3 and the second screening component 4. The end of the connector 13 of the first screening component 3 and the second screening component 4 is higher than the corresponding other end, which can facilitate the plastic particles to move from one end to the other end by gravity, thereby continuously moving downward without additional power, saving energy and reducing costs.
[0026] The first screening component 3 includes a screening screen 7 and a collection frame 8. The collection frame 8 is fixed on the rotating frame 15. The screening screen 7 is snapped and fixed to the top of the collection frame 8. The snap-fit design makes it easy to remove the screening screen 7, so that screening screens with different diameter meshes can be replaced. This means that different types of plastic particles can be used. The screening screen 7 separates plastic particles from impurities. At the same time, larger diameter plastic particles roll through the surface of the screening screen 7 until they fall into the extrusion equipment body 1, while smaller diameter impurities fall into the collection frame 8 through the mesh of the screening screen 7, thus collecting the impurities.
[0027] The end of the collection frame 8 away from the connector 13 is connected to a limiting component 16. The limiting component 16 includes a support plate 17 and a threaded rod 18. The support plate 17 is fixed to one end of the collection frame 8. The threaded rod 18 passes through the support plate 17 and is threadedly engaged. One end of the threaded rod 18 is fixedly connected to a friction pad 19. One end of the friction pad 19 is in contact with the inner side of the screening hopper 2. The friction between the friction pad 19 and the screening hopper 2 can ensure the tilt angle of the collection frame 8, thereby fixing the position of the collection frame 8. One end of the threaded rod 18 is fixedly connected to a handwheel. The handwheel can be used to easily rotate the threaded rod 18, increase the lever arm, and reduce the force required to rotate the threaded rod 18.
[0028] The side of the collection frame 8 is provided with a discharge port 9. Several feeding ports are located in the same vertical plane, so that impurities inside the collection frame 8 can be discharged through the discharge port 9. The discharge port 9 is located at the end of the side of the collection frame 8 near the limiting component 16, so that all impurities inside the collection frame 8 can be discharged. The discharge port 9 is connected to a sealing part 10 by threads. The sealing part 10 can seal the discharge port 9. At the same time, the threaded design makes it easy to remove and clean the inside of the collection frame 8.
[0029] An opening 11 is provided on the side of the screening hopper 2 near the discharge port 9. The projections of several discharge ports 9 onto the plane of the opening 11 are all within the area enclosed by the opening 11, thus facilitating simultaneous operation of all discharge ports 9 through the opening 11. A sealing door 12 is hinged at the opening 11, which serves to seal the screening hopper 2 during material discharge, preventing plastic particles from falling through the opening 11. A socket 20 is provided on one side of the screening hopper 2, and a plug 21 is slidably provided on one side of the sealing door 12. The socket 20 and the plug 21 are plugged in and fitted together to fix the sealing door 12 and the opening 11, thereby ensuring the stability of the sealing door 12 and the screening hopper 2. The socket 20 and the plug 21 are also easy to operate.
[0030] Working principle:
[0031] In use, the user adds plastic granules into the screening hopper 2 through the inlet at the top of the screening hopper 2. The plastic granules first come into contact with the first screening component 3 and fall onto the screening screen 7 of the first screening component 3. Due to the large diameter of the plastic granules, they will roll on the screening screen 7. Since the screening screen 7 is arranged at an angle, the plastic granules will roll towards the first opening 5 under the action of gravity. Impurities will fall into the collection frame 8 through the mesh of the screening screen 7 and be collected by the collection frame 8. The plastic granules that pass through the first opening 5 will fall onto the second screening component 4. The second screening component 4 performs secondary filtration on the plastic granules and impurities, and then enters the next layer of the first screening component 3 through the second opening 6. This process is repeated until the plastic granules fall into the extrusion equipment body 1. The extrusion equipment body 1 processes the plastic granules. The addition of multiple screening screens 7 increases the contact time between the plastic granules and the screening screens 7, thereby ensuring the screening effect and the purity of the material added to the extrusion equipment body 1, thus ensuring the precision of the processed product.
[0032] When cleaning the collection box 8 is required, the plug 21 and socket 20 are separated, and the sealing door 12 is rotated to allow the user to easily open the opening 11. The user can then open the sealing part 10 to allow the discharge port 9 to be discharged. Since the discharge port 9 is located at the lower end of the side of the collection box 8, impurities inside the collection box 8 can be easily discharged by gravity, thus ensuring the cleanliness of the inside of the collection box 8 and facilitating subsequent collection.
[0033] By rotating the threaded rod 18, which is threadedly engaged with the support plate 17, the threaded rod 18 moves relative to the support plate 17. This causes the threaded rod 18 to move the friction pad 19, which then separates from the screening hopper 2. This allows adjustment of the angle of the collection frame 8, thereby controlling the movement speed of the plastic particles on the screening screen 7 to meet different requirements. Furthermore, the screening screen 7 and the collection frame 8 are snap-fitted together, facilitating easy separation and replacement with screening screens 7 of different diameters to meet the needs of different types of plastic particles and increase practicality.
