Description

Technical Field

[0001] This utility model relates to the field of extruder welding technology, specifically a welding device for a twin-screw extruder. Background Technology

[0002] During the assembly of a twin-screw extruder, the base needs to be welded according to the extruder's specifications to ensure the overall stability of the extruder during use.

[0003] Traditional welding methods typically employ fixed-station welding, requiring the welding cable to be dragged across the ground. This operation is cumbersome, and the welding cable is prone to tangling as the welding position changes, affecting overall welding efficiency and hindering the subsequent movement of the welded base. Furthermore, existing fixtures are mostly designed for standard parts and are difficult to adapt to the base specifications of different extruder models. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a welding device for a twin-screw extruder, in order to solve the problems mentioned in the background art. In the traditional welding method, which is usually a fixed-position welding method, the welding cable needs to be dragged on the ground, which is cumbersome. Moreover, as the welding position changes, the welding cable is prone to tangling, which affects the overall welding efficiency and is not conducive to the subsequent movement of the welded base. At the same time, existing fixtures are mostly designed for standard parts and are difficult to adapt to the base specifications of different models of extruders.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for a twin-screw extruder, comprising a movable frame, four movable wheels installed at the four corners of the lower end of the movable frame, a welding auxiliary structure installed on one side of the upper end of the movable frame, and a welding fixing structure installed inside the movable frame;

[0006] The welding auxiliary structure includes: a support plate, a welding machine, a support frame, a bearing seat, a lifting rod, a rotating rod, a movable frame, and a fixed frame;

[0007] The support plate is fixedly installed on one side of the movable frame, the welding machine is placed on the upper part of the support plate, the support frame is fixedly installed on one side of the upper end of the movable frame, the bearing seat is fixedly embedded in the center of the upper end of the support frame, one end of the hoisting rod is movably embedded in the bearing seat, the rotating rod is movably embedded in the other side of the hoisting rod through the bearing, the movable frame is fixedly installed at the lower end of the rotating rod, and the fixed frame is fixedly installed at the lower end of the hoisting rod.

[0008] As a preferred embodiment of the welding device for a twin-screw extruder according to this utility model, the welding and fixing structure includes: a bearing plate, a lead screw, two internal thread moving blocks, two first clamping plates, four fixing blocks, four support rods, and four second clamping plates;

[0009] The bearing plate is fixedly installed at the center of the movable frame. The center of the lead screw is movably embedded in the bearing plate, and both ends of the lead screw movably pass through both sides of the movable frame. The two internally threaded moving blocks are movably fitted onto both ends of the lead screw. The two first clamping plates are respectively installed on the upper ends of the two internally threaded moving blocks. The four fixed blocks are respectively installed on the side walls of the movable frame. One end of each of the four support rods movably passes through the side wall of the four fixed blocks. The four second clamping plates are respectively installed on the top ends of the four support rods.

[0010] As a preferred embodiment of the welding device for a twin-screw extruder of this utility model, four fixing components are installed on the side walls of the four fixing blocks, and the four fixing components include: four fixing plates and four positioning screws;

[0011] The four fixing plates are respectively installed on the side walls of the four fixing blocks, and the four positioning screws are respectively movably embedded in the four fixing plates.

[0012] As a preferred embodiment of the welding device for a twin-screw extruder according to this utility model, the connection position between the fixing plate and the positioning screw is machined with internal threads.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the setting of the welding device for the twin-screw extruder has a reasonable structural design;

[0017] The four-wheel design at the bottom of the mobile frame enables the device to be quickly moved to the equipment site. The welding position can be changed according to the needs of the site. The welding machine is integrated into the support plate, reducing the equipment handling process. The hoisting rod achieves horizontal rotation through the bearing seat. The rotating rod drives the mobile frame to rotate horizontally. The fixed frame and the mobile frame work together to fix the welding cable. The angle of the welding cable can be adjusted according to different welding positions, solving the problem of dragging on the ground affecting subsequent welding. This allows the welding torch to cover weld seams at any angle on the workpiece.

[0018] The system uses a bidirectional threaded screw to drive two internal threaded moving blocks to move synchronously, which in turn causes the L-shaped first clamping plate to clamp the workpiece from both sides, adapting to bases of different diameters. The four support rods can be independently adjusted in spacing and locked in position by positioning screws. Together with the L-shaped second clamping plate, they form a multi-point fixing system to prevent workpiece displacement or deformation during welding and ensure the overall welding stability of the base.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] In this technical solution, a welding device for a twin-screw extruder includes a movable frame 1, four movable wheels 2 are installed at the four corners of the lower end of the movable frame 1, a welding auxiliary structure is installed on one side of the upper end of the movable frame 1, and a welding fixing structure is installed inside the movable frame 1.

[0027] The welding auxiliary structure includes: support plate 3, welding machine 4, support frame 5, bearing seat 6, lifting rod 7, rotating rod 8, movable frame 9, and fixed frame 10;

[0028] Support plate 3 is fixedly installed on one side of movable frame 1. Welding machine 4 is placed on the upper end of support plate 3. Support frame 5 is fixedly installed on one side of upper end of movable frame 1. Bearing seat 6 is fixedly embedded in the center of upper end of support frame 5. One end of lifting rod 7 is movably embedded in bearing seat 6. Rotating rod 8 is movably embedded in the other side of lifting rod 7 through bearing. Movable frame 9 is fixedly installed at the lower end of rotating rod 8. Fixed frame 10 is fixedly installed at the lower end of lifting rod 7.

[0029] In this technical solution, when welding and assembling the extruder, the operator first moves the device to the designated position using the four casters 2 at the four corners of the lower end of the movable frame 1. Then, according to the specifications of the extruder, the raw material of the base is placed on the upper end of the welding fixed structure. Next, the welding machine 4 on the upper end of the support plate 3 is powered on, and the negative terminal of the welding machine 4 is connected to the movable frame 1. The conductivity of the metal of the movable frame 1 ensures the conductivity of the raw material. Then, the positive welding cable of the welding machine 4 is passed through the fixed frame 10 and the movable frame 9 in sequence. During the welding process, the operator holds the welding torch and performs welding operations on the raw material of the base. As the welding position changes, the overall angle of the lifting rod 7 can be changed under the action of the bearing seat 6 in the support frame 5, which adjusts the position of the welding cable, making it easier for the operator to perform the welding operation. Furthermore, the angle of the movable frame 9 at the lower end of the lifting rod 7 can be changed by the rotating rod 8, which prevents the welding cable from bending and being damaged, and ensures the overall service life of the welding equipment.

[0030] In some technical solutions, reference Figure 1 The welded fixing structure includes: bearing plate 11, lead screw 12, two internal thread moving blocks 13, two first clamping plates 14, four fixing blocks 15, four support rods 16 and four second clamping plates 17.

[0031] The bearing plate 11 is fixedly installed at the center of the movable frame 1. The screw 12 is movably embedded in the bearing plate 11 at the center, and its two ends movably pass through both sides of the movable frame 1. The two internal threaded moving blocks 13 are movably fitted onto both ends of the screw 12. The two first clamping plates 14 are respectively installed on the upper ends of the two internal threaded moving blocks 13. The four fixing blocks 15 are respectively installed on the side walls of the movable frame 1. One end of the four support rods 16 movably passes through the side walls of the four fixing blocks 15. The four second clamping plates 17 are respectively installed on the top ends of the four support rods 16.

[0032] In this technical solution, when welding and fixing the base material, the worker places the materials at both ends of the base on the upper ends of the two first clamping plates 14, turns the screw 12 in the bearing plate 11 to change the distance between the two internal thread moving blocks 13 on the upper end of the screw 12, until the two first clamping plates 14 drive the materials at both ends to the designated position. Then, the position of the four support rods 16 in the four fixing blocks 15 is changed to adjust the distance between the four second clamping plates 17. Then, the materials on the other two sides of the base are placed on the upper ends of the four second clamping plates 17. Through the cooperation of the first clamping plates 14 and the second clamping plates 17, all the materials of the base are fixed.

[0033] In some technical solutions, reference Figure 1 Four fixing components are installed on the side walls of the four fixing blocks 15. The four fixing components include: four fixing plates 18 and four positioning screws 19.

[0034] Four fixing plates 18 are respectively installed on the side walls of four fixing blocks 15, and four positioning screws 19 are respectively movably embedded in the four fixing plates 18.

[0035] In this technical solution, when adjusting the spacing of the second clamping plate 17, the position of the support rod 16 within the fixing block 15 is changed. Then, the positioning screw 19 within the fixing plate 18 is turned until the bottom end of the positioning screw 19 contacts the top end of the support rod 16. The position of the support rod 16 and the second clamping plate 17 is fixed by the friction between the positioning screw 19 and the support rod 16.

[0036] In some technical solutions, reference Figure 1 The fixed plate 18 is machined with internal threads at the connection position with the adjusting screw to strengthen the locking force of the support rod 16 and ensure clamping rigidity. The first clamping plate 14 and the second clamping plate 17 are both L-shaped, which clamp the workpiece from both sides to accommodate screws of different diameters. The lead screw 12 is a bidirectional threaded lead screw 12. The two internal thread moving blocks 13 have opposite thread directions, driving the two internal thread moving blocks 13 to move synchronously.
