Description

Technical Field

[0001] The utility model relates to the field of twin-screw extruders, in particular to a hoisting structure for disassembling and assembling a discharging device of an extruder. Background Art

[0002] Twin-screw extruder is a kind of molding processing equipment for extruded products. It is developed on the basis of single-screw extruder. It has been widely used in the molding processing of extruded products due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics. Twin-screw extruder consists of several parts such as transmission device, feeding device, barrel and screw, and the discharge device at the tail end of the barrel is the decisive component for the final molding of the finished product.

[0003] Since the twin-screw extruder is a large-scale mechanical equipment, it is heavy and its parts are also very heavy. Since the discharging equipment includes easily worn equipment such as filter screens and die heads, it often needs maintenance and repair. Most of the existing discharging equipment is installed by disassembly and docking with the twin-screw extruder body. However, the existing technology lacks tools to assist the docking of the discharging equipment, resulting in certain troubles in the disassembly and assembly of the discharging equipment.

[0004] Therefore, a lifting structure for disassembling and assembling a discharging device of an extruder is provided to solve the above-mentioned problem. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a lifting structure for disassembling and assembling a discharging device of an extruder, aiming to solve the problem that most of the existing discharging equipment proposed in the background technology is detachably docked and installed with a twin-screw extruder body, but the prior art lacks tools for assisting the docking of the discharging equipment, resulting in certain troubles in disassembling and assembling the discharging equipment.

[0007] (II) Technical solution

[0008] To achieve the above purpose, the utility model provides the following technical solutions: a lifting structure for disassembling and assembling a discharging device of an extruder, comprising a lifting mechanism installed at the tail end of a twin-screw extruder body for lifting the discharging device:

[0009] In order to facilitate the installation and adjustment of the heavier discharger, the lifting mechanism includes a support seat installed on the side wall of the rear end of the twin-screw extruder body, a support rod is installed on the support seat, a lifting arm is rotatably sleeved on the support rod, and a lifting rod for hanging the discharge device is movably installed on the end of the lifting arm away from the support rod. By pushing the discharge device, the lifting rod pushes the lifting arm to rotate, so that the lifting arm drives the support rod to rotate on the support seat, so that the discharger can be moved to one side of the twin-screw extruder body, and can also be moved to the rear of the twin-screw extruder body, which is convenient for disassembly and docking, saving time and effort.

[0010] Preferably, in order to facilitate the disassembly and assembly of the boom and the discharging device, the bottom end of the boom extends into the discharging device and is screwed to the discharging device, and an anti-slip head is fixedly installed on the top of the boom. The boom can be removed from the discharging device by rotating the boom, and the anti-slip head is used to resist the top of the boom to prevent it from falling off, providing support, which is safe and reliable.

[0011] Preferably, in order to more conveniently push the boom, a handle is fixedly installed on the top of the boom. The boom can be dragged back and forth by holding the handle to prevent danger caused by hand slippage, and dragging the boom is more labor-saving.

[0012] Preferably, in order to be able to lift and lower the discharge device, the lifting structure also includes a lifting mechanism, which includes a lifting groove installed between the side wall of the twin-screw extruder body and the support seat, and a screw threaded with the support seat and a motor installed at one end of the screw are movably installed in the lifting groove. The screw is driven to rotate by the output end of the motor, and the screw drives the support seat to move up and down in the lifting groove, so that the height of the discharge device on the support seat can be adjusted at will to adapt to the installation position of the rear end of the twin-screw extruder body, which is convenient for the overall maintenance work and safer.

[0013] Preferably, in order to further improve the stability of the support seat when it is at a high place, a mounting hole is opened on the outer wall of the lifting groove, and a limiting support plate is installed on the mounting hole by means of bolts. After adjusting the position of the support seat at a high place, the limiting support plate is installed at the mounting hole so that the top of the limiting support plate is just in contact with the bottom of the support seat, which can not only further stabilize the support seat, but also prompt the support seat to be in a raised position, so as to facilitate alignment with the discharging device.

[0014] (III) Beneficial effects

[0015] The lifting structure pushes the discharging device so that the hanging rod pushes the hanging arm to rotate, thereby causing the hanging arm to drive the support rod to rotate on the supporting seat, so that the discharging device can be moved to one side of the twin-screw extruder body or to the tail of the twin-screw extruder body, which is convenient for disassembly and docking, saving time and effort.

[0016] The hoisting structure drives the screw to rotate through the output end of the motor, and the screw drives the support seat to move up and down in the lifting slot, so that the height of the discharge device on the support seat can be adjusted at will to adapt to the installation position of the rear end of the twin-screw extruder body, which is convenient for the overall maintenance work and safer.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] This embodiment provides a lifting structure for disassembling and assembling an extruder discharge device, such as Figure 1-3 As shown, the hoisting structure includes a hoisting mechanism 3 installed at the tail end of the twin-screw extruder body 1 for hoisting the discharge device 2:

[0026] When in use, by pushing the discharging device 2, the suspension rod 34 pushes the suspension arm 33 to rotate, so that the suspension arm 33 drives the support rod 32 to rotate on the support seat 31, so that the discharging device 2 can be moved to one side of the twin-screw extruder body 1, and the discharging device 2 is pushed again in the opposite direction, and the discharging device 2 can be moved to the tail of the twin-screw extruder body 1 through the suspension arm 33, which is convenient for disassembly and docking, saving time and effort.

[0027] Furthermore, the bottom end of the suspension rod 34 extends into the discharge device 2 and is screwed to the discharge device 2, and an anti-slipping head 35 is fixedly installed on the top of the suspension rod 34. When in use, the suspension rod 34 can be removed from the discharge device 2 by clamping the notch outside the anti-slipping head 35 with a wrench and rotating the suspension rod 34. The anti-slipping head 35 is used to resist the top of the suspension arm 33 to prevent slipping, provide support, and is safe and reliable.

[0028] Furthermore, a handle 36 is fixedly mounted on the top of the boom 33. When in use, the boom 33 can be dragged back and forth by holding the handle 36 to prevent the danger caused by hand slippage, and dragging the boom 33 is more labor-saving.

[0029] Example 2

[0030] Different from Example 1, Figure 1 , Figure 2 and Figure 3 As shown, the lifting structure also includes a lifting mechanism 4, which includes a lifting groove 41 installed between the side wall of the twin-screw extruder body 1 and the support seat 31, and a screw 42 screwed to the support seat 31 and a motor 43 installed at one end of the screw 42 are movably installed in the lifting groove 41.

When the discharge device 2 needs to be disassembled, the output end of the motor 43 is rotated in the opposite direction, and the screw 42 drives the support seat 31 to move downward in the lifting groove 41, and the discharge device 2 on the support seat 31 is lowered to the bottom surface, so that the discharge device 2 can be disassembled, which is safer and more reliable.

[0032] Furthermore, a mounting hole 44 is formed on the outer wall of the lifting slot 41 , and a limited support plate 45 is mounted on the mounting hole 44 by means of bolts.

[0033] When in use, after adjusting the position of the support seat 31 at a high altitude, the limit support plate 45 is installed at the mounting hole 44 by means of bolts, so that the top of the limit support plate 45 is just in contact with the bottom of the support seat 31, which can not only further stabilize the support seat 31, but also prompt the support seat 31 to rise to a higher position, making it easier to align the discharge device 2.
