Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a filter-type screw extruder. Background Technology

[0002] During the extrusion molding process, the raw materials often contain impurities such as metal scraps, sand particles, and unmelted plastic lumps due to their wide range of sources and diverse processing stages. If these impurities are not effectively filtered, they will seriously affect the quality of plastic products.

[0003] When defects such as pits and dents appear on the surface of plastic products, they greatly affect the product's appearance. Internal impurities can also weaken the product's structural strength, causing it to lose strength when subjected to pressure or tension, making it prone to cracking and breakage.

[0004] Traditional screw extruders have certain limitations in filtering impurities. In terms of filtration effect, they mostly use simple filter screens, which are difficult to accurately and comprehensively intercept impurities of different sizes and shapes. Tiny impurities can easily penetrate the filter screen, leaving residual defects in plastic products. Cleaning the filter device often requires manual disassembly after the machine is stopped, which is a cumbersome and time-consuming process. Moreover, impurities deep in the filter screen are difficult to remove completely. As production scale expands and product quality requirements increase, these limitations become more and more prominent, making it difficult to meet the ever-increasing production demands.

[0005] Therefore, this utility model proposes a filter-type screw extruder. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a filter-type screw extruder.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a filter-type screw extruder, comprising:

[0008] An extrusion assembly, comprising a first drive motor, a second sleeve, an extrusion head, and a threaded rod, wherein the threaded rod is rotatably connected inside the second sleeve, the first drive motor is located on one side of the second sleeve, the extrusion head is located on the other side of the second sleeve, and a feeding hopper is fixedly connected to the top of the second sleeve.

[0009] The base assembly consists of a fixed platform disposed below the second sleeve and an extrusion sleeve. The fixed platform is connected to the bottom of the first drive motor. A fixed bracket is disposed between the second sleeve and the fixed platform. The top of the fixed bracket is provided with the extrusion sleeve that is sleeved on the outside of the second sleeve.

[0010] The filter assembly consists of a filter cover and a filter box located on top of the hopper. The filter box is located inside the filter cover. Fixed plates are provided on both sides of the filter cover and the filter box. A telescopic damping element is provided between two fixed plates that are on the same vertical line. A filter hole is opened at the bottom of the filter box. An agitator roller is rotatably connected inside the filter box. Trigger frames are provided on both sides of the filter box. Connecting seats are provided on both sides of the filter cover located on the trigger frames. An eccentric block is provided on the side of the connecting seat closest to the trigger frame.

[0011] Furthermore, a second drive motor is provided on the other side of the connecting seat, and the output end of the second drive motor is connected to the eccentric block.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: A second drive motor is carefully set on the other side of the connecting seat. This layout is very ingenious. The second drive motor has excellent performance, strong power and stable operation. Its output end is precisely connected to the eccentric block. When the motor starts running, the stable power output can efficiently drive the eccentric block to rotate at high speed. The eccentric block thus produces regular eccentric motion, which in turn causes a specific vibration effect, providing key assistance for the efficient operation of related equipment and greatly improving the overall working efficiency of the equipment.

[0013] Furthermore, multiple stirring rollers are provided, and each of the multiple stirring rollers has a gear at one end that passes through the filter box, and the multiple gears are meshed and connected to each other.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: In the design of the filter box, multiple stirring rollers are set, which greatly improves the comprehensiveness and efficiency of stirring. Gears are set at one end of each stirring roller that runs through the filter box, and these gears are meshed and connected. In this way, when one stirring roller is driven to run, the meshing transmission between the gears can drive the other stirring rollers to rotate synchronously. This linkage mechanism makes the stirring operation more coordinated, the material is fully stirred in the filter box, effectively avoids stirring dead corners, and ensures that the filtration and stirring effect reaches the best state.

[0015] Furthermore, a third drive motor is provided on the side of the filter box away from the gear, and the output end of the third drive motor is connected to one of the stirring rollers.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: A third drive motor is strategically positioned on the side of the filter box furthest from the gears. This motor boasts powerful performance and excellent stability. Its output is closely connected to one of the stirring rollers. When the third drive motor starts, it provides stable and powerful power to the connected stirring roller. Furthermore, through the meshing transmission between gears, it drives the other stirring rollers to operate in coordination. This not only ensures efficient mixing but also allows the material to be uniformly mixed within the filter box, significantly improving the overall effect of filtration and mixing.

[0017] Furthermore, the bottom of the fixed platform is provided with a mounting bracket, and there are four mounting brackets in total. The four mounting brackets are arranged in a rectangular shape, and each of the four mounting brackets has a mounting hole.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: The bottom of the fixed platform is equipped with four mounting brackets arranged in a rectangular pattern. This layout provides a stable support structure for the fixed platform, ensuring that it remains stable under various working conditions and avoiding shaking and displacement. The mounting holes opened on each mounting bracket play an important role. Through these mounting holes, the fixed platform can be conveniently and firmly installed on the target plane using matching bolts, nuts and other connecting parts, which greatly improves the convenience and flexibility of installation and meets the installation needs in different scenarios.

[0019] Furthermore, there are two extrusion sleeves, and the diameter of the two extrusion sleeves is adapted to the outer wall diameter of the sleeve.

[0020] The beneficial effects of adopting the above-mentioned further solution are: with the close cooperation of the extrusion sleeve, the sleeve can be effectively and precisely limited. In actual use scenarios, whether it is the high-speed operation of material extrusion or the frequent start-up and shutdown of equipment, the extrusion sleeve can firmly restrict the sleeve, prevent it from shaking, and ensure that the entire process is stable and efficient.

[0021] Furthermore, the output end of the first drive motor is connected to the threaded rod.

[0022] The beneficial effects of adopting the above-mentioned further solution are as follows: The output end of the first drive motor is closely connected to the threaded rod. This connection method brings many advantages to the operation of the equipment. When the first drive motor is started, it can drive the threaded rod to rotate efficiently with stable and strong power. When the threaded rod rotates, the thread characteristics can be used to achieve precise linear displacement transmission. This not only provides stable power for the movement of related parts of the equipment, ensuring the orderly progress of material conveying, processing and other links, but also allows for precise adjustment of the operation of the threaded rod by controlling the motor speed and direction, thereby improving the flexibility and controllability of equipment operation.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, the eccentric block is first driven to rotate by the second drive motor. When the eccentric block rotates, it contacts the trigger frame, causing the trigger frame to move the filter box downward. At this time, the trigger frame retracts, reducing the distance between the filter box and the filter cover. Furthermore, when the eccentric block and the trigger frame are misaligned and separated, the filter box is driven to reset upward under the action of the telescopic damping component, realizing cyclic shaking. During the shaking process, the material enters the interior of the hopper through the filter hole, achieving the filtration effect before the material processing process.

[0025] 2. In this utility model, the stirring roller is further driven to rotate under the action of the third drive motor. At this time, multiple stirring rollers are meshed and connected to each other under the action of gears, so that when one stirring roller rotates, it drives the other stirring rollers to rotate. At this time, the material is broken up under the action of the stirring rollers so that it can pass through the filter holes better in the future and avoid the material from clumping and clogging the filter holes.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a filter-type screw extruder, comprising:

[0036] The extrusion assembly 2 consists of a first drive motor 21, a second sleeve 22, an extrusion head 23, and a threaded rod 24. The threaded rod 24 is rotatably connected inside the second sleeve 22. The first drive motor 21 is located on one side of the second sleeve 22, and the extrusion head 23 is located on the other side of the second sleeve 22. The top of the second sleeve 22 is fixedly connected to a feeding hopper 25.

[0037] The base assembly 1 consists of a fixed platform 11 located below the second sleeve 22 and an extrusion sleeve 131. The fixed platform 11 is connected to the bottom of the first drive motor 21. A fixed bracket 13 is provided between the second sleeve 22 and the fixed platform 11. The top of the fixed bracket 13 is provided with the extrusion sleeve 131 sleeved on the outside of the second sleeve 22.

[0038] The filter assembly 3 consists of a filter cover 31 mounted on top of the feed hopper 25 and a filter box 32. The filter box 32 is located inside the filter cover 31. Fixing plates 314 are provided on both sides of the filter cover 31 and the filter box 32. A telescopic damping element 322 is provided between two fixing plates 314 on the same vertical line. A filter hole 323 is provided at the bottom of the filter box 32. A stirring roller 33 is rotatably connected inside the filter box 32. Trigger frames 332 are provided on both sides of the filter box 32. Connecting seats 311 are provided on both sides of the filter cover 31 located on the trigger frames 332. An eccentric block 313 is provided on the side of the connecting seat 311 closest to the trigger frame 332. A second drive motor 312 is provided on the other side of the connecting seat 311. The output end of motor 312 is connected to eccentric block 313, and the output end of first drive motor 21 is connected to threaded rod 24. First, under the action of second drive motor 312, eccentric block 313 is driven to rotate. When eccentric block 313 rotates, it contacts trigger frame 332, causing trigger frame 332 to drive filter box 32 to move downward. At this time, trigger frame 332 retracts, reducing the distance between filter box 32 and filter cover 31. Further, when eccentric block 313 and trigger frame 332 are misaligned and separated, under the action of telescopic damping element 322, filter box 32 is driven to reset upward, realizing cyclic shaking. During the shaking process, material enters the interior of feed hopper 25 through filter hole 323, realizing the filtration effect before material processing.

[0039] Furthermore, such as Figures 2-3 As shown: Multiple stirring rollers 33 are provided, and each stirring roller 33 has a gear 331 at one end of its passage through the filter box 32. The gears 331 are meshed with each other. A third drive motor 321 is provided on the side of the filter box 32 away from the gears 331. The output end of the third drive motor 321 is connected to one of the stirring rollers 33. Under the action of the third drive motor 321, the stirring roller 33 is driven to rotate. At this time, the multiple stirring rollers 33 are meshed with each other under the action of the gears 331, so that when one stirring roller 33 rotates, it drives the other stirring rollers 33 to rotate. Under the action of the stirring rollers 33, the material is broken up so that it can pass through the filter holes 323 better and avoid the material from clumping and clogging the filter holes 323.

[0040] The above solutions still have the problem of fixing the mounting platform 11, such as... Figure 3As shown: In this solution, the bottom of the fixed platform 11 is provided with mounting brackets 12. There are four mounting brackets 12 in total, and the four mounting brackets 12 are arranged in a rectangular shape. Each of the four mounting brackets 12 has a mounting hole 121. There are two extrusion sleeves 131, and the diameter of the two extrusion sleeves 131 is adapted to the outer wall diameter of the sleeve 22. The four mounting brackets 12 at the bottom of the fixed platform 11 are arranged in a rectangular shape. This layout provides a stable support structure for the fixed platform 11, ensuring that it can remain stable under various working conditions and avoiding shaking and displacement. The mounting holes 121 on each mounting bracket 12 play an important role. Through these mounting holes 121, using matching bolts, nuts and other connecting parts, the fixed platform 11 can be conveniently and firmly installed on the target plane, which greatly improves the convenience and flexibility of installation and meets the installation needs in different scenarios.
