Description

Technical Field

[0001] This utility model relates to the field of extruder feeding, and more particularly to a feeding device for a plastic extruder. Background Technology

[0002] Plastic extruders are key equipment in the plastics processing industry, widely used in the manufacture of various plastic products such as pipes, profiles, and films. One of their core components is the feeding device, which is responsible for feeding plastic raw materials (granules, powders, or fragments) into the extruder's feed inlet at a stable speed and in a uniform quantity.

[0003] However, in actual production, with the diversification of market demands and technological advancements, existing feeding devices face several challenges. One major limitation is their difficulty in flexibly adjusting the amount of material fed into the extruder each time. In most cases, the feeding rate is controlled by preset parameters, which, once set, are difficult to adjust quickly according to real-time needs. This means that if product specifications need to be changed or different types of plastic raw materials need to be processed, it may be necessary to stop the machine to reset or replace some components, which not only increases operational complexity but may also affect the overall efficiency of the production line.

[0004] Therefore, it is necessary to provide a feeding device for a plastic extruder to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figures 1 to 5 A feeding device for a plastic extruder includes:

[0029] Frame main body 1;

[0030] The hopper 2 is fixedly connected to the surface of the frame body 1;

[0031] The rotating discharge assembly includes a fixed frame 5, a rotating wheel 7, a storage tank 8, a sliding plate 9, a discharge port 21, and a feed port 22. Multiple storage tanks 8 and sliding plates 9 are provided. The fixed frame 5 is fixedly connected to the lower end of the hopper 2. The feed port 22 is opened on the surface of the fixed frame 5. The discharge port 21 is opened on the surface of the fixed frame 5. The rotating wheel 7 is rotatably connected to the inner wall of the fixed frame 5. Multiple storage tanks 8 are opened on the surface of the rotating wheel 7. Multiple sliding plates 9 are slidably connected to the inner wall of the storage tank 8.

[0032] Adjustment components are set within the main frame 1;

[0033] A scale assembly, with the scale set on the surface of the fixed frame 5;

[0034] The cover plate assembly is located inside the hopper 2.

[0035] In the specific implementation process, plastic granules are first poured into the hopper 2. Then, the raw material falls through the feed inlet 22 into the storage tank 8 on the surface of the rotating wheel 7. After the motor 6 is started, the rotating wheel 7 rotates, driving the storage tank 8 to move. When the storage tank 8 containing raw material rotates to the discharge port 21, the raw material will fall from the discharge port 21 into the extruder feed inlet, achieving quantitative conveying. This design controls the amount of material fed each time through the periodic movement of the rotating wheel 7 and the fixed volume of the storage tank 8. At the same time, the sliding plate 9 can slide within the storage tank 8 to adjust the actual volume, further improving the material control accuracy and solving the limitation of traditional feeding devices that cannot flexibly adjust the feeding amount.

[0036] refer to Figures 1 to 5 As shown, a motor 6 is fixedly connected to the surface of the fixed frame 5, and a control rod is fixedly connected to the output end of the motor 6. The control rod is fixedly connected to the surface of the rotating wheel 7.

[0037] It should be noted that after the motor 6 starts, it drives the control lever to rotate, and the control lever directly drives the rotating wheel 7 to rotate at a constant speed, so that the storage tank 8 passes through the inlet 22 and the outlet 21 according to a fixed cycle, thereby achieving uniform delivery of raw materials.

[0038] refer to Figures 1 to 5 As shown, the adjustment assembly includes a rotating disk 10, an arc-shaped groove 11, a sliding rod 12, a connecting rod 13, a rotating rod 14, and a control button 15. Multiple arc-shaped grooves 11, sliding rods 12, and connecting rods 13 are provided. The rotating disk 10 is rotatably connected to the frame body 1. Multiple arc-shaped grooves 11 are formed on the surface of the rotating disk 10. Multiple sliding rods 12 are slidably connected to the inner walls of the multiple arc-shaped grooves 11. Multiple connecting rods 13 are fixedly connected to both ends of the multiple sliding rods 12, and every two connecting rods 13 are fixedly connected to the surface of one of the sliding plates 9. One end of the rotating rod 14 movably passes through the fixed frame 5 and one end of the rotating wheel 7, and one end of the rotating rod 14 is fixedly connected to the surface of the rotating disk 10. The control button 15 is fixedly connected to one end of the rotating rod 14.

[0039] It should be noted that during operation, one hand holds the rotating wheel 7 to prevent it from shaking, while the other hand rotates the control knob 15. The control knob 15 drives the rotating rod 14 to rotate. The rotating rod 14 is connected to the rotating disk 10 and makes it rotate. The four arc-shaped grooves 11 are distributed in a circular array on the surface of the rotating disk 10. The sliding rod 12 slides in the arc-shaped grooves 11, which drives the connecting rod 13 to move, and finally pushes the sliding plate 9 to slide in the storage tank 8, changing the effective volume of the storage tank 8, thereby accurately controlling the amount of material fed each time.

[0040] refer to Figures 1 to 5As shown, the scale assembly includes scale bars 18 and pointers 19. Multiple scale bars 18 are provided, and all scale bars 18 are fixedly connected to the surface of the fixed frame 5. The pointers 19 are fixedly connected to the circumferential surface of the rotating rod 14.

[0041] It should be noted that during operation, when the rotating disk 10 rotates, it drives the pointer 19 to move synchronously. The pointer 19 points to the scale bar 18 on the surface of the fixed frame 5. The user can set the rotation angle of the rotating disk 10 as needed. For example, the user can set the rotation of one scale to correspond to a certain reduction or increase in the volume of raw materials in the storage tank 8, so as to quickly determine the change in the actual amount of material fed.

[0042] refer to Figures 1 to 5 As shown, the cover plate assembly includes a baffle 3, a handle 4, and a slot 20. The slot 20 is formed on the surface of the hopper 2. The baffle 3 is slidably connected to the inner wall of the slot 20, and the handle 4 is fixedly connected to the surface of the baffle 3.

[0043] It should be noted that during operation, the baffle 3 is pushed into the hopper 2 along the slot 20 to close the feed inlet and prevent the raw material from getting damp or contaminated; when adding material, pull the handle 4 to pull out the baffle 3 and open the feed inlet.

[0044] refer to Figures 1 to 5 As shown, multiple anti-slip strips 16 are fixedly connected to the surface of the control button 15.

[0045] It should be noted that when the user rotates the control knob 15 during operation, the anti-slip strip 16 can effectively prevent the fingers from slipping, especially in wet or gloved environments, ensuring the stability and accuracy of the adjustment action.

[0046] The working principle of the feeding device for a plastic extruder provided by this utility model is as follows:

[0047] After the raw material is poured into the hopper 2, the feed inlet is sealed by the cover plate assembly baffle 3 and the slot 20 to prevent overflow. The raw material enters the storage tank 8 on the surface of the rotating wheel 7 through the feed inlet 22. The motor 6 is started to drive the rotating wheel 7 to rotate. When the storage tank 8 rotates to the discharge port 21, the raw material falls into the extruder feed inlet. By manually rotating the control knob 15 through the adjustment assembly rotating disk 10, sliding rod 12, etc., the sliding plate 9 slides in the storage tank 8, dynamically adjusting the effective volume of the storage tank 8. The adjustment amount is intuitively indicated by the scale assembly pointer 19 and scale bar 18, realizing flexible control of the feeding amount. This design solves the limitation of traditional feeding devices that cannot dynamically adjust the feeding amount according to actual needs, and improves the feeding accuracy and production adaptability of the extruder.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
