Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a translation mechanism of an extruder. Background Art

[0002] The extruder is one of the important equipments needed for plastic extrusion molding production. When the extruder is installed, the bottom of the base is usually equipped with a wheel seat, which allows the extruder to be moved more conveniently for maintenance and transfer.

[0003] In the prior art, there are generally two modes of roller mechanisms set under the extruder: the first is to set universal wheels, such as a drying extruder that is easy to move disclosed in CN201911253364.X. The universal wheels have the characteristics of multi-angle rotation, which can flexibly move the extruder, but this method has the following disadvantages: the universal wheels are designed to rotate 360 ​​degrees to provide high maneuverability. This means that they have complex rotating mechanisms, including bearings, brackets and fulcrums. These components need to disperse the force when bearing weight, and the force when bearing weight needs to be dispersed in multiple directions, which will result in a relatively small force that can be borne in each direction, and the weight of the extruder is very heavy, which makes the universal wheels easily crushed;

[0004] The second is to set a linear roller, such as a mobile plastic extruder disclosed in CN201310171313.9. The linear roller has a simple structure, the force is concentrated in a single direction, and the load-bearing components are more solid, so the load-bearing capacity is stronger. However, since it can only move in a straight line, the extruder is not flexible to move. Utility Model Content

[0005] The utility model aims to solve the problem pointed out in the background technology that the universal wheel is flexible but poor in load-bearing capacity, and the linear roller has excellent load-bearing capacity but is not flexible, and proposes an extruder translation mechanism.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An extruder translation mechanism, the extruder includes a frame and an extruder body installed on the frame, the translation mechanism includes at least three roller switching mechanisms, the roller switching mechanism includes a support rod, the middle part of the support rod is rotatably connected to the frame through a third hinge, the support rod is provided with a first linear roller on one side of the third hinge, and a second linear roller on the other side of the third hinge, the axis of the first linear roller is perpendicular to the axis of the second linear roller, and the translation mechanism includes a power mechanism that can drive the support rod to rotate around the third hinge.

[0008] The axis of the first linear roller is arranged along the length direction of the extruder body, and the axis of the second linear roller is arranged along the width direction of the extruder body.

[0009] The power mechanism comprises a power telescopic rod, one end of which is rotatably connected to the frame via a first hinge, and the other end of which is rotatably connected to one end of a support rod via a second hinge.

[0010] There are four roller switching mechanisms, which are distributed at the four corners of the frame. Every two roller switching mechanisms correspond to a group of power mechanisms. The power mechanism includes a power telescopic rod and a connecting rod. One end of the power telescopic rod is rotatably connected to the frame through a first hinge, and the other end of the power telescopic rod is rotatably connected to the middle part of the connecting rod through a second hinge. The connecting rod is arranged along the width direction of the extruder body, and the connecting rod is fixed to two support rods.

[0011] A plurality of the power telescopic rods are arranged in linkage.

[0012] A plurality of legs are fixedly connected to the bottom of the frame. When the support rod is in a horizontal state, the bottom ends of the legs are higher than the lowest points of the first linear roller and the second linear roller.

[0013] The utility model proposes an extruder translation mechanism, which has the beneficial effect that: a plurality of roller switching mechanisms are installed at the bottom of the frame of the device, wherein the roller switching mechanism has a first linear roller and a second linear roller whose axes are vertically arranged; when the first linear roller supports the entire device through the power mechanism, the entire device can translate in the front and rear directions; when the second linear roller supports the entire device through the power mechanism, the entire device can translate in the left and right directions, thereby realizing translation work in the entire plane; since the device adopts linear rollers as support, it has excellent load-bearing capacity, and the device can realize both translation of the plane and excellent supporting performance.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2 , an extruder translation mechanism, the extruder includes a frame 2, an extruder body 1 installed on the frame 2, the translation mechanism includes at least three roller switching mechanisms, if three roller switching mechanisms are used, then the three roller switching mechanisms need to be distributed in a triangle, so as to stably support the extruder body 1 and the frame 2, the roller switching mechanism includes a support rod 9, the middle part of the support rod 9 is rotatably connected to the frame 2 through a third hinge 10, the support rod 9 is located on one side of the third hinge 10 and is equipped with a first linear roller 8, and is located on the other side of the third hinge 10 and is equipped with a second linear roller 11, the axis of the first linear roller 8 is perpendicular to the axis of the second linear roller 11, and the translation mechanism includes a power mechanism that can drive the support rod 9 to rotate around the third hinge 10.

[0019] refer to Figure 1 , Figure 2 A plurality of roller switching mechanisms are installed at the bottom of the frame 2 of the device, wherein the roller switching mechanism comprises a first linear roller 8 and a second linear roller 11 whose axes are vertically arranged. When the first linear roller 8 supports the entire device through the power mechanism, the entire device can translate in the front-to-back direction. When the second linear roller 11 supports the entire device through the power mechanism, the entire device can translate in the left-to-right direction, thereby realizing translation work in the entire plane. Since the device adopts linear rollers as support, it has excellent load-bearing capacity. The device can realize translation of the plane and have excellent supporting performance.

[0020] As an implementation mode, the axis of the first linear roller 8 is arranged along the length direction of the extruder body 1, and the axis of the second linear roller 11 is arranged along the width direction of the extruder body 1, and translation in different directions can be achieved by replacing different linear roller supports.

[0021] As an embodiment, the power mechanism includes a power telescopic rod 5, one end of the power telescopic rod 5 is rotatably connected to the frame 2 through a first hinge 4, and the other end of the power telescopic rod 5 is rotatably connected to one end of a support rod 9 through a second hinge 6. The support rod 9 is driven by the extension and retraction of the power telescopic rod 5 to move around the third hinge 10, thereby realizing the supporting effect of different linear rollers. The power telescopic rod 5 can use a hydraulic cylinder, and preferably multiple power telescopic rods 5 are arranged in linkage to extend or shorten at the same time.

[0022] refer to Figure 2There are four roller switching mechanisms, which are distributed at the four corners of the frame 2. Every two roller switching mechanisms correspond to a group of power mechanisms. The power mechanism includes a power telescopic rod 5 and a connecting rod 7. One end of the power telescopic rod 5 is rotatably connected to the frame 2 through a first hinge 4, and the other end of the power telescopic rod 5 is rotatably connected to the middle part of the connecting rod 7 through a second hinge 6. The connecting rod 7 is arranged along the width direction of the extruder body 1, and the connecting rod 7 is fixed to two support rods 9. The two support rods 9 are driven to move simultaneously by one power telescopic rod 5, thereby reducing the number of power telescopic rods 5.

[0023] refer to Figure 1 A plurality of legs 3 are fixedly connected to the bottom of the frame 2. When the support rod 9 is in a horizontal state, the bottom end of the leg 3 is higher than the lowest point of the first linear roller 8 and the lowest point of the second linear roller 11. When the extruder is working normally, it is supported by the legs 3. When translation is required, the first linear roller 8 or the second linear roller 11 is changed to support the ground through the telescopic power telescopic rod 5 to achieve translation and extend the service life of the linear roller.
