Description

Rub weld device for bundle-band of packing machine

The present invention relates to a device for melting and connecting a bundle band of a packaging machine by generating a high temperature by friction.

Conventional general packaging machines place articles to bind the band on the workbench, wrap the band around the article as a band bundling device to bind it tightly, and then heat and dissolve the band as a band welding device where the band is polymerized. After bonding, cut. In the conventional packaging machine welding apparatus, most of the welding machines use an electric welding method to insert the polymerized part of the band in the center of the electric heater to dissolve the part, and then remove the electric heater and cool the melted joint.

However, in the conventional method of joining the band by conventional electric welding, since the electric heater is kept at a high temperature continuously during the operation after the packaging machine is operated, the temperature is too high, it is easy to be damaged, and there is a lack of heat for this. Effectively, the purpose of heat welding could not be achieved, so that the service life was shortened, and there was a danger of unexpected contact caused by high heat.

The present invention is devised to solve the above-mentioned conventional problems,

The purpose of this method is to eliminate this defect by changing the conventional method of the bundle band of the packaging machine by electrothermal welding to a kind of mechanical friction welding.

As a technical configuration for achieving the above object, the bundled band friction welding apparatus of the present invention is to install the upper band substrate and the lower band substrate in a suitable place of the main body of the packaging machine to firmly hold the polymerized portion of the bundle band. The upper band substrate is fixed and does not move, and the lower band substrate is connected to the pressurization hole underneath so as to move up and down so that the pressing hole moves the lower band substrate up and down. In addition, the lower band substrate is provided with a friction generating port for moving the lower band substrate back and forth quickly back and forth after inserting the polymerized portion of the band. This friction generating port combines a motor, two belt cars, an eccentric shaft, a weight bar, and a connecting rod, and when the motor rotates, the weight bar Joints installed at the tip of the head) move the lower band substrate back and forth quickly by the action of the eccentric shaft, so that the lower band substrate applies friction to the polymerized part of the band. The high temperature is generated, dissolved, and cooled, whereby it can be bonded firmly.

The friction dissolution device of the bundle band of the packing machine in this paper applies friction to the band by rapidly reciprocating back and forth between the upper band substrate and the lower band substrate of the band sandwiched between the upper band substrate and the lower band substrate. Since high temperature is generated and dissolved, the polymerized part is firmly bonded when cooled.

A comparatively preferred embodiment of the bundled band friction welding device of the present packaging machine includes the upper band substrate 10, the pressurizing opening 20, and the friction operation mechanism (see Fig. 1 and Fig. 2) at a suitable place of the packaging main body (1). 30) is configured by installing.

Among them, the upper band substrate 10 is fixed near the place where the bundle band of the packaging base body 1 welds the polymerization part, and the bumpy and coarse upper band trapping fixing surface 11 is provided on the end surface thereof.

Among them, the pressure port 20 has a pedestal 21 at the lower portion thereof, and a roller 22 is installed on the upper portion of the upper portion of the pressurizing member 20 so as to move in the direction of the upper band substrate 10 together with the pedestal 21. The seat 21 is moved by the operation of the elastic rubber (not shown in the figure), but the operation of the elastic rubber is a well-known technique and its detailed description is omitted.

As shown in Fig. 2, the friction operation tool 30 has a packaging body 1, and the packaging body 1 has a bottom plate 311, which is fixed to a suitable place of the packaging body 1. The end of the bottom plate 311 is fixed to the U-shaped motor fixing plate 312 and the bearing seat 313, and the motor 32 is fixed on the motor fixing plate 312.

This motor 32 has an output shaft 321. The output shaft 321 is axially connected to the motor fixing plate 312 at a right angle.

As shown in Fig. 3, the bearing seat 313 is connected to the eccentric shaft 33 in a concentric manner, and the eccentric shaft 33 almost forms an eccentric portion 331 at the middle thereof. 331 is eccentrically connected to the distal end of the weight bar (34) is fixed. The other end of the weight rod 34 connects the connecting rod 35, and the connecting rod 35 has a U-shaped sphere 351, and this U-shaped sphere 351 ) Is movable on the outer circumferential surface of the roller 22 of the pressure port 20, and the lower band substrate 36 is firmly squeezed to the connecting ingot 35 again. 2 and 4, the lower end of the lower band substrate 36 forms an uneven and coarse lower band trapping fixing surface 361, and the upper band trapping fixing surface 11 of the upper band substrate 10 is formed. To face. Further, the first belt car 37 and the second belt car 38 are fixedly installed at appropriate positions of the output shaft 321 and the single-shaft shaft 33 of the motor 32, and the belt 39 ) Is hooked around these two belt cars so that the output of the motor 32 is transmitted to the eccentric shaft 33.

The following describes how to use this paper and its operation.

First, reference is made to FIGS. 2, 3 and 4.

When the article placed on the packaging machine is wound by the band 3 and bundled, the band 3 polymerizes in a suitable place of the packaging base body 1. And friction welding device

(2) is started, and the base 21 of the pressure port 20 is moved to the upper band substrate 10 to apply pressure.

At the same time, the connection band 35 and the lower band substrate 36 of the friction operation tool 30 are moved, so that the lower band capturing fixing surface 361 of the lower band substrate 36 has a polymerized portion of the band 3 formed on the upper band substrate ( It is pressed against the upper band catching fixed surface 11 of 10). At this time, when the motor 32 of the friction ball 30 is first started and rotated, the output is sequentially passed through the output shaft 321, and the first belt car 37, the belt 39, and the second belt car. 38 rotates and moves, and the eccentric shaft 33 is rotated. Thus, the rod 34 on the eccentric portion 331 of the eccentric shaft 33 generates a biasing operation to reciprocate the connecting rod 35 at its end back and forth to push the roller 22. The lower band substrate 36, which slides back and forth on the outer circumferential surface of the circumferential surface) and is thus connected to the connecting rod 35, also reciprocates back and forth quickly under the polymerization portion of the band 3 to perform friction action against the band 3. Add. The polymerized portion of the band 3 is inserted into the upper and lower band substrates 10 and 36 at an appropriate pressure, and the two substrates have the band 3 as the upper and lower band trapping fixing surfaces 11 and 361. Since the motor 32 is started when the motor 32 is started, the polymerized portion of the band 3 is melted due to frictional action in a very short time and becomes molten. Joined to finish the work.

The present invention made of the above-described configuration has the following effects.

The upper and lower substrates 10 and 36 of the present invention are formed by the high-speed polymerization of the bands sandwiched between them by rapid mechanical action, which is welded and cooled and welded firmly. Therefore, there is no risk of high temperature contact accompanying them. In addition, there is no risk of damage to the equipment or physical injury to the workforce resulting from overheating caused by this conventional electric heating. In addition, there is no phenomenon of lack of temperature, the service life is relatively long, and the welding quality is stable.
