JPS5920639A - Easy disassembling portable extruder - Google Patents

Abstract

PURPOSE:To enable a portable extruder to be easily disassembled, delivered, and assembled again by attaching main constituent parts, such as a motor, a coupling, a decelerator, bearings, a cylinder, etc., to the upside of a supporting base for an extruder. CONSTITUTION:An operating board serving as a stand 8 and a base 6 having a guide projection 11 on its longitudinal direction are fixed to a base 9 with wheels by means of fixing tools, e.g., bolts, etc. A bearing 5, a decelerator 4, a coupling 3, and a motor 2 are orderly set along the guide projections 11 of the base 6 by fitting their grooves formed on the downsides on the projections 11 and then fixed to the base 6 by clamping the bolts 13 by means of a U- shaped clamper 12. A cylinder 1 is connected to the bearing 5 and a hopper 10 is connected to the cylinder 1. An extruder can thus be easily assembled and can also be simply disassembled manually when delivered.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an extruder, and more particularly to an extruder that can be disassembled for portability.

Conventional portable extruders are often used for marking electric wires or extruding multicolors, but they do not have a small and lightweight structure that is easy to assemble and disassemble by a single operator. That is, even if the size of the screw is reduced to reduce the weight, the assembly itself becomes complicated, and the electric motor and reduction gear as the driving device are quite heavy and difficult to handle, so disassembly is difficult. For this reason, the device must be moved in an assembled state, and is often subject to dimensional restrictions on the path of movement or the location of use.

On the other hand, if the size of the screw is reduced to make the entire device small and lightweight, it can be made portable, but extruders with screws of such size often do not have sufficient capacity, which poses practical problems.

An object of the present invention is to provide a practical portable extruder that can be disassembled into its own portable component parts and is easy to assemble.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a side view of one embodiment of the present invention. The embodiment shown in FIG. 1 is composed of an extruder main body and a support stand that supports the extruder main body in a detachable manner, and furthermore, the extruder can be disassembled.

That is, the extruder has a cylinder 1 containing a built-in screw (not shown), an electric motor 2 for driving the screw, a coupling 3, a reducer 4, and a bearing 5 connected in series, and a hopper 10 connected to the cylinder 1. All of these have dimensions and weight that can be carried by humans and can be disassembled.

The support stand consists of a wheeled base 9, an operation panel/stand 8 attached to it, and a base 6 fixed on it.
The control panel 7 for the electric motor 2 is arranged in a well-balanced manner taking into account the position of the entire center of gravity after assembly, and all of these are assembled with appropriate fixings such as bolts, so that the control panel 7 for the electric motor 2 As shown in the figure, the base 7 has a longitudinal direction.
A guide protrusion 11 is provided in the opposite direction, and grooves corresponding to the guide protrusion 11 are formed on the lower surfaces of the electric motor 2, the compression ring 3, the speed reducer 4, and the bearing portion 5, respectively.

Therefore, after assembling the support part, for example, the U shown in FIG.
The bearing part 5 is fixed to the base 6 by tightening the bolt 13 using the shape clamp member 12, and the reducer 4, the coupling 3, and the electric motor 2 are sequentially installed on the guide protrusion 11 and fixed in the same manner. By fixing each to the base 6 with tools, assembly can be easily performed. Furthermore, the cylinder 1 is connected to the bearing part 5, and the hopper 10 is connected to it.
The extruder is completed by assembling.

Although the clamp 11 is shown as a separate member in FIG. 2, if it is provided integrally with the base 6, fixing and disassembly will be easier.

As mentioned above, the extruder of the present invention can be disassembled in all main parts, and the dimensions and weights of the individual parts are within the range that can be handled by one worker. Therefore, assembly can be easily performed by simple fixing with bolts, and it has an extremely effective practical effect.
