Description

Technical Field

[0001] The utility model relates to the technical field of extrusion equipment, and more specifically to a twin-screw extrusion equipment for winding films. Background Art

[0002] When the existing technology recycles winding films, operations such as cleaning and pulverizing, drying, extrusion granulation, and cooling are carried out on the recycled winding films, so that the waste winding films are re-converted into reusable plastic particles. In the extrusion granulation process, an extruder is required to implement this step. Due to its good performance such as exhaust and stable extrusion, the twin-screw extrusion equipment is widely used in this process;

[0003] However, when the existing twin-screw extrusion equipment is in operation, only a simple feed hopper structure is provided, and the feeding work is completed by relying on the self-falling of the winding film fragments. This leads to the situation that some winding film fragments may adhere to the inner wall of the feed hopper due to uneven drying, excessive moisture in themselves or other factors, and cannot fall. Manual feeding operation is still required, which is time-consuming and laborious. Therefore, a device that can automatically and efficiently complete the raw material addition operation and avoid some raw materials from adhering to the inner wall of the feed hopper is needed. Summary of the Utility Model

[0004] The utility model provides a twin-screw extrusion equipment for winding films, and its beneficial effect is that it can automatically and efficiently complete the raw material addition operation and avoid some raw materials from adhering to the inner wall of the feed hopper.

[0005] A twin-screw extrusion equipment for winding films includes a twin-screw extruder main body. A feed hopper is provided on the twin-screw extruder main body. A rotating rod is connected to the feed hopper. The rotating rod can rotate around a virtual axis. A sliding rod is slidably connected to the rotating rod. A knocking head is connected to the sliding rod. A compression spring is fixedly connected between the sliding rod and the rotating rod. A rotating ring is connected to the feed hopper. A plurality of arc-shaped convex blocks are fixedly connected to the rotating ring.

[0006] The heights of the plurality of arc-shaped convex blocks gradually increase in the counterclockwise direction.

[0007] The rotating ring is rotatably connected to the feed hopper.

[0008] It also includes a toothed ring fixedly connected to the rotating ring. A motor is fixedly connected to the feed hopper. A gear is fixedly connected to the output shaft of the motor. The gear can be meshed with the toothed ring. Description of the Drawings

[0009] The following further describes the present utility model in detail with reference to the drawings and specific implementation methods.

[0010] Figure 1 and Figure 2 is a schematic diagram of the overall structure of a twin-screw extrusion equipment for winding films;

[0011] Figure 3 It is a schematic structural diagram of the sliding rod;

[0012] Figure 4 It is a schematic structural diagram of the swivel ring;

[0013] Figure 5 It is a schematic structural diagram of the knocking head. Specific embodiments

[0014] As Figures 1-5 shown:

[0015] It includes the twin-screw extruder main body 401. A feed hopper 402 is provided on the twin-screw extruder main body 401. A rotating rod 104 is connected to the feed hopper 402. The rotating rod 104 can rotate about a virtual axis. A sliding rod 201 is slidably connected to the rotating rod 104. A knocking head 202 is connected to the sliding rod 201. A compression spring 203 is fixedly connected between the sliding rod 201 and the rotating rod 104. A swivel ring 301 is connected to the feed hopper 402. A plurality of arc-shaped convex blocks 302 are fixedly connected to the swivel ring 301.

[0016] Put the shredded winding film pieces after cleaning, crushing and drying operations into the feed hopper 402. Subsequently, the shredded winding film pieces can gradually and automatically fall, and the twin-screw extruder main body 401 is used to melt and extrude the shredded winding film pieces. Then, through subsequent cooling and granulation operations, it forms finished plastic particles, thereby achieving the treatment effect of the recycled winding film. Using the twin-screw extruder main body 401 to process the shredded winding film pieces is a well-known technology in the prior art, and there are already various devices in this field to achieve this function, so it will not be elaborated here at length;

[0017] During the process of putting the shredded winding film pieces into the feed hopper 402 and making the shredded winding film pieces automatically fall, the rotating rod 104 continuously rotates counterclockwise. During the movement of the rotating rod 104, when the knocking head 202 moves to a position where it can contact a certain arc-shaped convex block 302, the arc-shaped convex block 302 will gradually exert a thrust on the knocking head 202, causing the sliding rod 201 to slide on the rotating rod 104. At this time, the compression spring 203 will continuously undergo compressive deformation. When the rotating rod 104 rotates past the position of this arc-shaped convex block 302, the compression spring 203 can push the sliding rod 201 to quickly reset, causing the knocking head 202 to quickly strike the swivel ring 301, applying a certain knocking force to the feed hopper 402, thereby causing the feed hopper 402 to vibrate slightly due to the knocking, effectively avoiding the situation where some shredded winding film pieces adhere to the inner wall of the feed hopper 402 and cannot slide automatically, and the need for manual feeding operation. During the rotation of the rotating rod 104, the knocking head 202 can perform frequent multiple knocking operations on the feed hopper 402 in cooperation with a plurality of arc-shaped convex blocks 302, thereby achieving the effect of facilitating the automatic and efficient completion of the raw material addition operation and avoiding some raw materials from adhering to the inner wall of the feed hopper.

[0018] As Figure 4 shown:

[0019] The heights of the multiple arc-shaped bumps 302 gradually increase in the counterclockwise direction.

[0020] The setting that the heights of the multiple arc-shaped bumps 302 gradually increase in the counterclockwise direction enables each arc-shaped bump 302 to push the percussion head 202 to slide different distances, that is, the compression spring 203 can deform to different degrees, so that the percussion head 202 can strike the feed hopper 402 with different forces, enabling the feed hopper 402 to have different degrees of percussion shock, thereby further avoiding the situation where some fragments of the winding film adhere to the inner wall of the feed hopper 402 and cannot slide off automatically.

[0021] As Figure 1 、 Figure 2 and Figure 4 shown:

[0022] The rotating ring 301 is rotatably connected to the feed hopper 402.

[0023] During the percussion vibration process, the rotating ring 301 can be periodically rotated clockwise on the feed hopper 402, thereby changing the positions of the multiple arc-shaped bumps 302 facing the feed hopper 402, so that the percussion source position can also be adjusted, and further improving the percussion effect on the feed hopper 402, and further avoiding the situation where some fragments of the winding film adhere to the inner wall of the feed hopper 402 and cannot slide off automatically.

[0024] As Figure 2 and Figure 4 shown:

[0025] It further includes a toothed ring 303 fixedly connected to the rotating ring 301. A motor 403 is fixedly connected to the feed hopper 402, and a gear 404 is fixedly connected to the output shaft of the motor 403. The gear 404 can mesh with the toothed ring 303.

[0026] When it is necessary to operate the toothed ring 303 to rotate, the output shaft of the motor 403 can be rotated, so that the output shaft of the motor 403 drives the gear 404 to rotate, thereby driving the toothed ring 303 to slide by the gear 404, and then driving the rotating ring 301 to rotate, achieving the effect of a higher percussion position.

[0027] As Figures 1-3 shown:

[0028] It further includes a connecting plate 101, and a rotating rod 104 is rotatably connected to the connecting plate 101.

[0029] When a knocking operation is required, the rotating rod 104 can be rotated on the connecting plate 101, so that the rotating rod 104 drives the sliding rod 201 to move, and the subsequent knocking work is completed by using the moving knocking head 202.

[0030] As Figure 3 shown:

[0031] The connecting plate 101 is provided with connecting threaded holes 102.

[0032] The connecting plate 101 is fixed on the upper side of the feed hopper 402 by screwing bolts into the connecting threaded holes 102, thereby providing support for the subsequent knocking work.

[0033] As shown in Figure 3:

[0034] A plurality of connecting threaded holes 102 are provided.

[0035] The arrangement of the plurality of connecting threaded holes 102 enables fixation to be completed by screwing bolts into the plurality of connecting threaded holes 102 during fixation, improving the stable fixation effect of the connecting threaded holes 102.

[0036] As Figure 3 shown:

[0037] The knocking head 202 is detachably connected to the sliding rod 201 by bolts.

[0038] The detachable connection between the knocking head 202 and the sliding rod 201 enables, during actual use, when the knocking head 202 is deformed due to multiple knocks and the subsequent knocking effect cannot be guaranteed, the knocking head 202 to be removed from the sliding rod 201 by loosening the bolts for replacement, thereby ensuring the knocking effect for a long time.

[0039] As Figure 2 shown:

[0040] The main body 401 of the twin-screw extruder is provided with a plurality of fixing threaded holes.

[0041] The main body 401 of the twin-screw extruder can be fixed by screwing bolts into the plurality of fixing threaded holes, thereby fixing the whole device.

[0042] As Figure 2 shown:

[0043] The feed hopper 402 is made of stainless steel.

[0044] The setting of stainless steel material can prevent the interior of the feed hopper 402 from rusting after long-term use, thus avoiding the situation that the subsequent finished product extrusion effect is affected.
