Description

Technical Field

[0001] This utility model relates to the field of plastic extruder feeding and filtration technology, specifically a plastic extruder feeding and filtration structure. Background Technology

[0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, while the downstream equipment that is matched with it, the plastic extrusion molding machine, is called the auxiliary machine. After more than 100 years of development, the plastic extruder has evolved from the original single screw to twin screw, multi screw, and even screwless models.

[0003] Plastic extruders are a common type of plastic processing equipment, widely used in various fields of plastic product processing. During the production process of plastic extruders, raw materials need to be fed and conveyed. However, common feeding equipment does not have a filtration function, so the raw materials may contain impurities, foreign objects, or excessively large particles. These impurities will affect the quality of plastic products and may even cause malfunctions in plastic processing equipment, making it difficult to carry out further processing operations on plastic products and reducing the quality of production. Utility Model Content

[0004] The purpose of this invention is to provide a feeding and filtering structure for a plastic extruder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding and filtering structure for a plastic extruder, including a support box, a filtering mechanism inside the support box, a cleaning mechanism on one side of the filtering mechanism, and a feeding cylinder on one side of the cleaning mechanism;

[0006] The filtration mechanism includes a motor, which is fixedly connected to the bottom of the inner wall of the support box. A drive gear is fixedly connected to the outer wall of the motor output shaft. A driven gear meshes with the outer ring of the drive gear. A rotating cylinder is fixedly connected to the inner ring of the driven gear. A discharge hopper is rotatably connected to the bottom end of the rotating cylinder. A filter screen is fixedly connected to the inner wall of the rotating cylinder. A connecting shaft is fixedly connected to the bottom of the inner wall of the discharge hopper. A long rod is fixedly connected to the outer wall of the connecting shaft. A cleaning plate is fixedly connected to the end of the long rod away from the connecting shaft. A cleaning frame is fixedly connected to the outer wall of the bottom end of the connecting shaft. An arc-shaped block is fixedly connected to the outer wall of the connecting shaft.

[0007] Preferably, the outer shape of the cleaning frame matches the inner wall shape of the discharge hopper, and the outer shape of the cleaning plate matches the inner wall shape of the rotating cylinder, so that the material discharge effect of the device can be further improved by the cooperation of the cleaning plate and the cleaning frame.

[0008] Preferably, the top of the support box has a through hole that matches the rotating cylinder, and the rotating cylinder is rotatably connected to the inner wall of the through hole, which supports the rotating cylinder and allows it to rotate stably.

[0009] Preferably, the discharge hopper is fixedly connected to the bottom of the support box, and the connecting shaft passes through the filter screen, so that the discharge hopper supports the connecting shaft. The raw material can be pushed and filtered by the arc-shaped block, which facilitates further processing and use of the plastic raw material.

[0010] Preferably, the cleaning mechanism includes an L-shaped block, which is fixedly connected to the top of the support box. The top of the L-shaped block has a slot, and a plug is inserted into the slot. A support ring is fixedly connected to the inner side of the L-shaped block, and a bolt is threaded into the plug. This allows the operator to easily disassemble the feed cylinder and clean the filtered impurities.

[0011] Preferably, the insert and the L-shaped block are threaded together on one side with a threaded hole, and the bolt is threaded into the inner wall of the threaded hole. Through the cooperation of the bolt and the threaded hole, the insert cannot be pulled out of the slot.

[0012] Preferably, the insert block is fixedly connected to the outside of the feed cylinder, and the bottom end of the support ring is rotatably connected to the top end of the rotating cylinder, which makes it easier for the staff to perform the feeding operation.

[0013] Compared with the prior art, the present invention provides a feeding and filtering structure for a plastic extruder, which has the following beneficial effects:

[0014] This plastic extruder feeding and filtering structure, through its set filtering mechanism, starts the motor, allowing the arc-shaped block to push the raw material accumulated on top of the filter screen for filtration, achieving the purpose of filtering the plastic raw material and achieving good processing quality. At the same time, the cleaning plate can scrape the inner wall of the rotating drum, reducing the amount of raw material sticking to the inner wall of the rotating drum. With the cooperation of the cleaning frame, the filtered raw material can be better discharged. Thus, the filtered plastic raw material can be further processed to achieve good processing quality and enhance the practicality of the device.

[0015] This plastic extruder feeding and filtering structure, through a cleaning mechanism, allows the bolts to be unscrewed from the inner wall of the threaded hole in the insert block, thereby removing the limiting effect on the insert block. Then, the insert block can be pulled out from the inner wall of the L-shaped block through the feed cylinder, realizing the disassembly of the feed cylinder. This not only cleans the impurities filtered from the top of the filter screen, but also achieves good disassembly efficiency, further improving the convenience of operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides the following technical solution: Example

[0027] Combination Figures 1 to 6 A feeding and filtering structure for a plastic extruder includes a support box 1, a filtering mechanism 3 is provided inside the support box 1, a cleaning mechanism 4 is provided on one side of the filtering mechanism 3, and a feeding cylinder 2 is provided on one side of the cleaning mechanism 4.

[0028] The filtration mechanism 3 includes a motor 31, which is fixedly connected to the bottom of the inner wall of the support box 1. A drive gear 32 is fixedly connected to the outer wall of the output shaft of the motor 31. A driven gear 33 meshes with the outer ring of the drive gear 32. A rotating cylinder 34 is fixedly connected to the inner ring of the driven gear 33. A discharge hopper 35 is rotatably connected to the bottom of the rotating cylinder 34. A filter screen 36 is fixedly connected to the inner wall of the rotating cylinder 34. A connecting shaft 37 is fixedly connected to the bottom of the inner wall of the discharge hopper 35. A long rod 38 is fixedly connected to the outer wall of the connecting shaft 37. A cleaning plate 39 is fixedly connected to the end of the long rod 38 away from the connecting shaft 37. A cleaning frame 301 is fixedly connected to the outer wall of the bottom end of the connecting shaft 37. An arc-shaped block 302 is fixedly connected to the outer wall of the connecting shaft 37.

[0029] Furthermore, the outer shape of the cleaning frame 301 matches the inner wall shape of the discharge hopper 35, and the outer shape of the cleaning plate 39 matches the inner wall shape of the rotating cylinder 34, so that the material discharge effect of the device can be further improved under the cooperation of the cleaning plate 39 and the cleaning frame 301.

[0030] Furthermore, the top of the support box 1 is provided with a through hole that matches the rotating cylinder 34. The rotating cylinder 34 is rotatably connected to the inner wall of the through hole, which provides support for the rotating cylinder 34 and allows it to rotate stably.

[0031] Furthermore, the discharge hopper 35 is fixedly connected to the bottom of the support box 1, and the connecting shaft 37 passes through the filter screen 36, so that the discharge hopper 35 supports the connecting shaft 37. The raw material can be pushed and filtered by the arc block 302, which facilitates further processing and use of the plastic raw material. Example

[0032] See Figures 1 to 6 Furthermore, based on Embodiment 1, the cleaning mechanism 4 further includes an L-shaped block 41, which is fixedly connected to the top of the support box 1. A slot 42 is provided on the top of the L-shaped block 41, and a plug 43 is inserted into the slot 42. A support ring 45 is fixedly connected to the inner side of the L-shaped block 41, and a bolt 44 is threadedly connected to the plug 43. This allows the staff to easily disassemble the feed cylinder 2 and clean the filtered impurities.

[0033] Furthermore, the insert block 43 and the L-shaped block 41 are threaded with threaded holes on one side, and the bolt 44 is threaded into the inner wall of the threaded hole. Through the mutual cooperation between the bolt 44 and the threaded hole, the insert block 43 cannot be pulled out of the slot 42.

[0034] Furthermore, the insert block 43 is fixedly connected to the outside of the feed cylinder 2, and the bottom end of the support ring 45 is rotatably connected to the top end of the rotating cylinder 34, which makes it easier for the staff to perform the feeding operation.

[0035] In actual operation, when this device is used and the plastic extruder needs to be fed, the raw material to be processed is first injected into the top of the feed cylinder 2. At the same time, the motor 31 can be started, so that the output shaft of the motor 31 can drive the drive gear 32 to rotate. The drive gear 32 drives the rotating cylinder 34 to rotate through the driven gear 33. Thus, the arc block 302 can push the raw material piled on the top of the filter screen 36 for filtration, achieving the purpose of filtering the plastic raw material and achieving good processing quality. At the same time, the cleaning plate 39 can scrape the inner wall of the rotating cylinder 34, reducing the situation of raw material sticking to the inner wall of the rotating cylinder 34. With the cooperation of the cleaning frame 301, the filtered raw material can be better discharged. Thus, the filtered plastic raw material can be further processed to achieve good processing quality and enhance the practicality of the device.

[0036] Subsequently, during prolonged use, when it is necessary to clean the impurities filtered at the top of the filter screen 36, firstly, the twisting block at one end of the bolt 44 will unscrew the bolt 44 from the inner wall of the threaded hole in the insert block 43, thereby removing the limiting effect on the insert block 43. Then, the insert block 43 can be pulled out from the inner wall of the L-shaped block 41 through the feed cylinder 2, thus disassembling the feed cylinder 2. This achieves both cleaning of the impurities filtered at the top of the filter screen 36 and good disassembly efficiency, further improving the convenience of operation.
