Description

Technical Field

[0001] This utility model belongs to the field of polymer material production technology, and in particular relates to a novel twin-screw extruder for polymer materials. Background Technology

[0002] Polymer materials are materials composed of compounds with relatively high molecular weights, typically above 10,000, and sometimes even reaching millions. These materials, with their unique structure and properties, have wide applications in numerous fields such as industry, agriculture, medicine, and daily life. During polymer processing, they must be transported using a bidirectional screw conveyor.

[0003] A search revealed an existing patent (publication number CN207657145U) that discloses a twin-screw extruder for automotive polymer materials, comprising a casing, a die head, and two sets of screws. The two sets of screws mesh with each other. The casing has a screw cavity to accommodate the two sets of screws. The casing also has multiple vacuum ports communicating with the screw cavities. The die head is located at one end of the casing, and the output end of the screw cavity corresponds to the die head. The die head includes a holding cavity that matches the shape of the extruded material from the two sets of screws and communicates with the output end of the screw cavity to maintain the shape of the extruded material; a transition cavity that communicates with the holding cavity to allow the extruded material to spread out; and multiple forming holes that communicate with the transition cavity to generate strips.

[0004] However, although the above scheme can achieve the extrusion purpose, the extruder does not have a corresponding feeding device at the feed port, so it is impossible to control the falling speed of the polymer material. Therefore, it is necessary to design a new type of twin-screw extruder for polymer materials. Utility Model Content

[0005] This invention provides a novel twin-screw extruder for polymer materials, which aims to solve the problem that although the extruder can achieve the extrusion purpose, it does not have a corresponding feeding device at the feed inlet, making it impossible to control the falling speed of the polymer material.

[0008] Preferably, the support plate is parallel to the bottom of the extruder body, and the bottom of the support plate is provided with an anti-slip pad.

[0009] Preferably, the support plate is provided with connecting grooves at each of the four diagonal points, and the connecting grooves correspond to the positions of the rollers.

[0010] Preferably, the material distribution plates are arranged in six pairs, and the material distribution plates are attached to the inner wall of the feed inlet.

[0011] Preferably, two sets of the baffles are symmetrically arranged, and the two sets of baffles completely close the feed inlet.

[0017] Example 1: A preferred embodiment of the novel twin-screw extruder for polymer materials provided by this utility model. Figures 1-5 As shown: A novel twin-screw extruder for polymer materials includes: an extruder body 1; a hydraulic cylinder 2 fixedly connected to the side of the extruder body 1; a support plate 3 fixedly connected to the output end of the hydraulic cylinder 2; a connecting groove 5 disposed at the bottom of the support plate 3; rollers 4 fixedly connected to the bottom of the extruder body 1; a maintenance cabinet 6 disposed on the surface of the extruder body 1; and two sets of feeding components 7 disposed at the top of the extruder body 1. The feeding components 7 can be used to control the feeding speed to achieve orderly feeding operation.

[0018] In this embodiment, when the extruder body 1 is in use, the device can be moved by the rollers 4 to improve the flexibility of movement. After being moved to the designated location, the hydraulic cylinder 2 can be opened to control the support plate 3 to descend. The support plate 3 then descends and contacts the ground, lifting the rollers 4, thereby achieving the effect of fixing the entire device. The connecting groove 5 can prevent the support plate 3 from blocking the rollers 4 when it is raised or lowered.

[0019] In a further preferred embodiment of the present invention, the feeding assembly 7 includes: a feed inlet 701 fixedly connected to the top of the extruder body 1; a placement groove 710 fixedly connected to the top of the feed inlet 701; a servo motor 702 fixedly connected to the side of the feed inlet 701; a distribution plate 703 fixedly connected to the output end of the servo motor 702; a bidirectional screw 704 rotatably connected to the side of the placement groove 710; a connecting plate 705 fixedly connected to the side of the placement groove 710; two sets of sliders 706 threadedly connected to the surface of the bidirectional screw 704; a baffle 707 fixedly connected to the top of the sliders 706 and slidably connected to the connecting plate 705; a rotating plate 708 rotatably connected to the inner wall of the connecting plate 705; and a cover plate 709 fixedly connected to the top of the rotating plate 708.

[0020] In this embodiment, the material to be fed into the extruder body 1 is placed inside the placement trough 710. In order to achieve orderly feeding, the distribution plate 703 can be rotated by the servo motor 702. Since the distribution plate 703 has six sets, the faster the distribution plate 703 rotates, the slower the material falls, and vice versa. By setting baffles 707, they can contact the rotating plate 708 and fix the open baffles 709. When it is necessary to close the placement trough 710 to achieve a dust prevention effect, the bidirectional screw 704 can be rotated to control the two sets of baffles 707 to move away from each other along the connecting plate 705 and disengage from the rotating plate 708. At this time, the two sets of baffles 709 can be closed to seal the top of the placement trough 710.

[0021] In a further preferred embodiment of this utility model, the support plate 3 is parallel to the bottom of the extruder body 1, and the bottom of the support plate 3 is provided with an anti-slip pad.

[0022] In this embodiment, the hydraulic cylinder 2 can be opened to control the support plate 3 to descend. The support plate 3 then descends and contacts the ground, lifting the roller 4, thereby achieving the effect of fixing the entire device.

[0023] In a further preferred embodiment of the present invention, a connecting groove 5 is provided at each of the four diagonal corners of the support plate 3, and the connecting groove 5 corresponds to the position of the roller 4.

[0024] In this embodiment, the connecting groove 5 can prevent the support plate 3 from blocking the roller 4 when it is raised or lowered.

[0025] In a further preferred embodiment of this utility model, six sets of material distribution plates 703 are arranged in a symmetrical manner, and the material distribution plates 703 are attached to the inner wall of the feed inlet 701.

[0026] In this embodiment, the material distribution plate 703 can be rotated by the servo motor 702. Since the material distribution plate 703 has six sets, the faster the material distribution plate 703 rotates, the slower the material falls, and vice versa.

[0027] In a further preferred embodiment of this utility model, two sets of baffles 709 are symmetrically arranged, and the two sets of baffles 709 completely close the feed inlet 701.

[0028] In this embodiment, the two sets of baffles 709 can be closed to seal the top of the placement slot 710 and prevent dust from falling into the interior of the placement slot 710.

[0029] In a further preferred embodiment of the present invention, the baffle 707 has an "L" structure, and the baffle 707 forms a sliding structure along the interior of the connecting plate 705 via a bidirectional screw 704.

[0030] In this embodiment, when the cover plate 709 is opened, the baffle 707 can be controlled to fit against the cover plate 709, thereby fixing the rotating plate 708.

[0031] In a further preferred embodiment of the present invention, after the baffle 707 moves, it fits into the rotating plate 708, and the rotating plate 708 is fixed by the baffle 707.

[0032] In this embodiment, by setting baffle 707, it can contact the rotating plate 708, and fix the opened baffle 709. When it is necessary to close the placement slot 710 to achieve the dustproof effect, the bidirectional screw 704 can be rotated to control the two sets of baffles 707 to move away from each other along the connecting plate 705 and to disengage from the rotating plate 708.

[0033] In summary, the support plate 3 can be used to lift the roller 4 to quickly fix the extruder body 1. Furthermore, the feeding component 7 not only enables orderly feeding, but also allows the placement slot 710 to be closed when the equipment is not in use, thus preventing dust and dirt from entering.
