JPH09314800A - Tension device for squeegee drive chain for traveling printing machine - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable the tension adjustment of a chain to be easily performed without the clogging of gauze at the time of ending a single squeegeeing process and especially, enable the tension device to be checked for a tension condition, stopped and held as it is at the top position of the squeegeeing process by fitting a mounting plate internally along a fitting face and adjusting the tension of the chain with the help of an adjusting bolt behind. SOLUTION: A right and a left vertical frame 25, 26 are fitted to a lower connecting support pillar 32 through a right and a left fitting plate 66, 67. This fitting is performed by internally fitting a mounting plate with a threaded hole for forcing an upper and a lower L protrusion to narrow and fastening the tension device 53. The tension device 53 fitted along the outer faces of the right and the left fitting plate 66, 67 has a U slot formed on the fitting face, into the center of which a lower sprocket 50 is fitted, and the sprocket 50 is borne by a shaft. The tension device 53 as a whole is caused to slide by loosening some for the slot part of adjusting bolts 57 which come into contact with the end part of the mounting plate and rotating the bolt, as that the tension of a chain 51 is adjusted.

Description

Detailed Description of the Invention

[0001]

[Industrial application] Aluminum left and right vertical frames 25.2
The present invention relates to a traveling type textile printing machine that uses a metal chain 51 that slides on the inner and outer peripheral surfaces of the sheet 6, to perform scavenging.

[0002]

2. Description of the Related Art Since the left and right vertical frames 25 and 26 are made of aluminum, the metal chain 51 that slides on the inner and outer peripheral surfaces of the left and right vertical frames 25 and 26 has a groove, which adversely affects the plastic wheel group 110. There is a problem when scavenging a traveling type printing machine, especially when using it on an inclined printing table with an inclined printing table,
Since the inverted V-shaped cage holder 44 is heavy, if it naturally falls due to its own weight, there is a risk that the dyeing paste will stick out and stain the fabric. Conditions are better if the printing table is flat or has a low inclination. If the scavenging drive motor is additionally provided with a brake, it will be held, but the chain 51 itself will inevitably extend. Conventional chain 5
Although the elongation of No. 1 was adjusted by the left and right screw bolts 45 connected to the cage carriage 41, the adjustment work took a long time and was not easy because it was taken out from the cage carriage 41 for internal installation.

[0003]

When the scavenging is performed by the left and right metal transmission chains 51, it will inevitably extend during long-term use. There was no problem when the detection was stopped, but after the stop, it fell due to its own weight, and it was detached and the detection was not retained, and the next process stopped and did not proceed. As a result, the dyeing paste may stick out and stain the fabric. Another chain 51
However, the cage carriage 41 stopped midway, causing a serious defect that stains the cloth. If the vertical frames 25 and 26 are aluminum molded products, the chain 51 is attached to the contact surface of the wheel group 110 to be slid.
If the wheel slides, a mark groove of the chain 51 is attached, and the wheel group 110
There was a case where the shaving was deformed and smoothness of the scavenging was hidden, but since it could be floated by adjusting the tension of the transmission chain 51, the above-mentioned problem could be solved at once. Further, if it is used for an inclined printing table, it is necessary to adjust the tension of the transmission chain 51 even with a drive motor with a brake.

[0004]

The chain tension device 53 is related to the mounting side mechanism, but is a method for easily adjusting it by utilizing the left and right vertical frames 25 and 26 and the lower mounting plates 66 and 67, which are partially opened on the side surfaces. It was invented as
By doing so, adjustment became extremely easy, and minute sag could be easily adjusted in a short time.

Lower connection support 32 mounting Lower mounting plate 66
Using the mounting surface 54 of 67, the sprocket with shaft 50
Was attached to form a U-shaped cross section, a long hole 55 was provided, and it was attached so that it could be easily adjusted by an adjusting bolt 57 on the rear side.

[0006]

[Operation] Since the structure is simplified and the fabric 2 is not soiled at the end of the scavenging 1 stroke and the gauze 35 is not clogged, it is possible to stop and hold the detection especially at the upper part of the scavenging, which is a problem in the inclined printing table. Became.
