Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a belt washing device for a screen printing machine.

[Conventional technology]

The screen printing machine (see Fig. 1) includes a printing section 2 consisting of an endless annular conveyor belt 1, and a cloth feeding section 3.
It consists of a drying section 4 and the like, and a screen frame 5 is placed on a conveyor belt to print on cloth A.

The belt washing device of this screen printing machine is intended to wash away dirt remaining on the conveyor belt, and is provided on the return path of the conveyor belt.

As shown in FIG. 4, a conventional belt washing device includes two horizontal brush rollers 31 that contact the surface of the belt, a plurality of water fountain pipes 32 that spray water toward the belt, and a belt drain plate. 33.

[The problem that the idea attempts to solve]

However, in the belt washing device of conventional screen printing machines, the contact between the brush roller and the belt is a line contact, and the brushing action ends in a short time, resulting in insufficient cleaning and defective products due to stains such as residual dye. There was an easy problem to solve.

This has become particularly noticeable in recent years as we entered the era of high-speed screen printing.

This idea was made in view of these conventional problems, and its purpose is to
The present invention aims to provide a belt washing device for a screen printing machine that can completely clean the belt by increasing the brushing action in response to higher speeds.

[Means to solve the problem]

In order to achieve the above object, the belt washing device of the screen textile printing machine according to the present invention includes a plate brush at the forefront, and the brushes are arranged at the rear of the plate brush and are formed with raised bristles on the top surface of a circular substrate. It consists of a disk-shaped brush that rotates on a vertical rotation axis at the center of the bottom surface of the substrate, and a drain plate is arranged behind these brushes, and each brush is provided perpendicular to the traveling direction of the conveyor belt and across its width. .

Further, the disc-shaped brush may have bristles arranged in a spiral shape.

[Effect]

In the belt washing device of the screen textile printing machine configured in this way, the plate brush removes fiber waste etc. in advance, allowing the disk-shaped brush to operate efficiently, and also because the brush is in planar contact with the entire width of the belt surface. The contact area is large and the brushing action is greatly increased.

In addition, when the hair bundles are arranged in a spiral, thread waste, cotton waste, etc. adhering to the brush can be naturally scattered and removed by the centrifugal force of the principle of a centrifugal pump.

〔Example〕

Figures 1 to 3 show an embodiment of this invention, which has a disc-shaped brush surface horizontally arranged in two rows arranged orthogonally to the traveling direction of an endless annular conveyor belt 1 of a screen printing machine. It is formed from a brush 6, a pair of fountain pipes 7 arranged before and after this brush row, a rubber drain plate 8 arranged at the rearmost part, and a plate brush 9 arranged at the frontmost part. The disk-shaped brush 6 is rotated by a vertical rotating shaft 10 provided at the center of the lower surface of the substrate, and the whole is mounted on a flat rectangular tray 11, so that cleaning water collects in the tray and is drained from a drain pipe 12.

The disk-shaped brush 6 has small nylon hair bundles 14 arranged vertically in a spiral arrangement on the flat upper surface of a circular base plate 13, and a transmission pulley 15 is attached to the lower end of a vertical rotating shaft protruding downward from a tray 11. The conveyor belts in the two rows rotate at high speed in opposite directions (see arrows in FIG. 2) via a drive belt (not shown), and a brushing action is performed over a wide area on the conveyor belt. The drive belt is also driven by a variable motor.

Two rows of disc-shaped brushes are arranged alternately and concentrated in a narrow space. In addition to the above-described arrangement of hair bundles in a spiral shape, this brush can also be used to implant hair evenly, and the number of rows and number of brush bodies can be appropriately selected depending on the purpose.

The draining plate 8 and the plate brush 9 are fixed by having their thin plate-like substrate fitted into a deep groove 16 provided on the side wall of the tray 11 so as to be able to move in and out, and can be attached to spare parts by sliding in the longitudinal direction. Changes can be made quickly.

The tray 11 is fixed on the base 17 and the base 1
The brush is moved up and down by a hydraulic cylinder 18 attached to the center of the conveyor belt 1 so that the brush comes into pressure contact with the conveyor belt 1 at a required pressure.

When using the belt washing device of the screen textile printing machine, the brushes make surface contact over a wide area with the conveyor belt, resulting in a large brushing action.
Furthermore, since the hair bundles are arranged and flocked in a spiral pattern, the centrifugal force based on the principle of a centrifugal pump is applied due to the high speed rotation, and thread waste, cotton waste, etc. adhering to the brush are scattered and removed along with the splashing water. Therefore, it is fully compatible with high-speed screen printing.

Further, there is an advantage that a plate brush is provided at the front end to remove lint and cotton waste in advance, and the plate brush and draining plate can be replaced with spare parts with a single touch.

[Effect of idea]

This idea is structured as described above, so
This produces the following effects.

In the belt washing device according to claim 1, since the brush is in surface contact with the conveyor belt over a wide area, a large brushing action can be exerted, and the belt is sufficiently washed to prevent the generation of defective products due to dirt. It is fully compatible with the era of high-speed screen printing.

In the belt washing device according to the second aspect of the present invention, the lint and lint adhering to the brushes during conveyor cleaning are automatically scattered and removed by centrifugal force, so that the brushes are less clogged and the number of times the brushes are cleaned is reduced. The operational efficiency of the textile printing machine increases.
