Description

Technical Field

[0001] This utility model belongs to the field of extruder screw manufacturing technology, and in particular relates to a support frame for extruder screw processing. Background Technology

[0002] Extruders are widely used in the mixing, extrusion, molding, and reaction processes of plastics, rubber, synthetic fibers, coatings, pulp, pharmaceuticals, and food processing. An extruder consists of one or two screws rotating within a barrel, propelling the material forward.

[0003] During extrusion, the dimensional design of each section of the screw has a significant impact on product quality. Therefore, the dimensional requirements for the extruder screw during processing are quite high. In existing technology, the screw is machined on a lathe. However, because the screw is relatively long and heavy, a support frame is required when machining it on a lathe. But existing support frames are cumbersome to adjust when dealing with screws of different diameters, and it is difficult to ensure concentricity. This results in large dimensional deviations in the machined product, affecting product quality.

[0004] To address this issue, we propose a support frame for extruder screw processing. Utility Model Content

[0005] The purpose of this invention is to solve the problem of insufficient concentricity of the screw in the prior art, and to propose a support frame for extruder screw processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support frame for processing an extruder screw includes a base and an arc-shaped locking cover hinged to one side of the top of the base. An upper locking frame is slidably mounted on the arc-shaped top surface of the locking cover. An upper adjustment component for driving the upper locking frame to move up and down is provided on the top surface of the locking cover. A lower locking frame is slidably mounted on the top surface of the base directly below the upper locking frame. A lower adjustment component for driving the lower locking frame to move up and down is provided inside the base. Rotating wheels are rotatably mounted on the center of the facing surfaces of the upper and lower locking frames.

[0008] The upper locking frame includes an upper support cover located in the middle, and arc-shaped upper limit rods are fixedly connected to both sides of the upper support cover, and the upper limit rods on both sides are staggered. The lower locking frame includes a lower support cover and a lower limit rod, and the upper limit rod and the lower limit rod on the same side are staggered.

[0009] Preferably, the upper locking frame and the lower locking frame are each provided with two rotating wheels, and the two rotating wheels on the upper locking frame are respectively rotatably disposed on both sides of the bottom surface of the upper support cover, and the two rotating wheels on the lower locking frame are respectively rotatably disposed on both sides of the top surface of the lower support cover.

[0010] Preferably, the lower adjustment assembly includes a threaded rod rotatably disposed in the middle of the top wall of the base, and the bottom of the lower support cover is threadedly sleeved on the top of the threaded rod. The base is provided with a drive assembly for driving the threaded rod to rotate. A first limiting rod is provided parallel to one side of the threaded rod, and the top of the first limiting rod is fixedly connected to the bottom surface of the lower support rod, and the bottom of the first limiting rod slides through the top wall of the base.

[0011] Preferably, the drive assembly includes a rotating rod rotatably disposed on one side of the bottom of the base, and the ends of the rotating rod and the threaded rod facing each other are fixedly fitted with mutually meshing bevel gears.

[0012] Preferably, the upper adjustment component includes a wing bolt rotatably disposed in the middle of the top surface of the upper support cover, and the upper end of the wing bolt is threaded through the locking cover.

[0013] Preferably, the bottom of the upper limit rod is lower than the top of the lower limit rod.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This support frame for extruder screw processing achieves screw height adjustment through a lower adjustment component and a lower locking frame, and fixes the screw through an upper adjustment component and an upper locking frame. The upper and lower limit rods, which are arranged in an alternating manner, enable adaptation to screws of different diameters. Compared with existing devices, this avoids the problem of insufficient concentricity caused by processing screws of different diameters, and improves the processing effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A support frame for extruder screw processing includes a base 1 and an arc-shaped locking cover 2 hinged to one side of the top of the base 1. The locking cover 2 can be locked to the base 1 by bolts. The above locking method is prior art and will not be described in detail. An upper locking frame 3 is slidably provided on the arc-shaped top surface of the locking cover 2. An upper adjustment component is provided on the top surface of the locking cover 2 to drive the upper locking frame 3 to move up and down. A lower locking frame 4 is slidably provided on the top surface of the base 1 directly below the upper locking frame 3. A lower adjustment component is provided inside the base 1 to drive the lower locking frame 4 to move up and down. Rotating wheels 5 are rotatably provided in the middle of the facing surfaces of the upper locking frame 3 and the lower locking frame 4.

[0021] The upper locking frame 3 includes an upper support cover 6 located in the middle, and arc-shaped upper limit rods 7 are fixedly connected to both sides of the upper support cover 6. The upper limit rods 7 on both sides are staggered. The lower locking frame 4 includes a lower support cover 8 and a lower limit rod 9. The upper limit rod 7 and the lower limit rod 9 on the same side are staggered.

[0022] Reference Figure 1-3 This extruder screw processing support frame, in use, places the screw on the lower locking frame 4, then rotates and locks the locking cover 2. At this time, the lower locking frame 4 is driven up and down by the lower adjustment component until the screw is horizontal. Then, the upper locking frame 3 is driven down by the upper adjustment component. At this point, the upper limit rod 7 and the lower limit rod 9 intersect, and the upper locking frame 3 continues to move down until the screw is fixed. The processing component then rotates and processes the screw. The rotating wheel 5 reduces the friction between the screw and the support frame, reducing the load on the processing component. It should be noted that the processing component is existing technology and may include a screw feeder and a screw cutter. The above-mentioned processing component is existing technology and will not be described in detail.

[0023] Two rotating wheels 5 are rotatably mounted on the upper locking frame 3 and the lower locking frame 4, respectively. The two rotating wheels 5 on the upper locking frame 3 are rotatably mounted on both sides of the bottom surface of the upper support cover 6, and the two rotating wheels 5 on the lower locking frame 4 are rotatably mounted on both sides of the top surface of the lower support cover 8. The two rotating wheels 5 provide stable support for the screw and facilitate its rotation.

[0024] Reference Figure 1-3 The lower adjustment assembly includes a threaded rod 10 rotatably disposed in the middle of the top wall of the base 1, and the bottom of the lower support cover 8 is threadedly sleeved on the top of the threaded rod 10. The base 1 contains a drive assembly for rotating the threaded rod 10. A first limiting rod 11 is provided parallel to one side of the threaded rod 10, with its top fixedly connected to the bottom surface of the lower support rod and its bottom slidingly penetrating the top wall of the base 1. This adjustment assembly drives the threaded rod 10 to rotate via the drive assembly, thereby achieving vertical adjustment of the lower support cover 8. The first limiting rod 11 limits the lower support cover 8, preventing it from rotating with the threaded rod 10.

[0025] Since the base 1 is generally slidably mounted on the slide rail in actual use, the drive assembly cannot be located on the bottom surface of the base 1. The drive assembly includes a rotating rod 12 rotatably mounted on one side of the bottom of the base 1, and the ends of the rotating rod 12 and the threaded rod 10 facing each other are fixedly fitted with bevel gears 13 that mesh with each other, so as to change the transmission direction through the bevel gears 13.

[0026] The upper adjustment assembly includes a wing bolt 14 rotatably disposed in the middle of the top surface of the upper support cover 6, and the upper end of the wing bolt 14 is threaded through the locking cover 2. The upper support frame is adjusted up and down by rotating the wing bolt 14, thereby adjusting the upper locking frame 3 up and down.

[0027] The bottom of the upper limit rod 7 is lower than the top of the lower limit rod 9, thereby limiting the upper limit rod 7 through the lower limit rod 9, preventing the upper support cover 6 from rotating with the butterfly bolt 14, and improving stability.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
