JPS5929115A - Embedding method of resin rod into synthetic resin roll - Google Patents

Abstract

PURPOSE:To fix plastic rods securely to any roll by inserting plastic rod ends into holes formed on the circumferential surface of a synthetic resin roll and driving in safety pins in a specific condition. CONSTITUTION:Multiple embedding holes 3, 3... are provided in rows on the outer circumference of a cylindrical roll 2 of polypropylene etc. and synthetic resin rods 4 and bundles 6 of synthetic resin haris are embedded alternately in the circumferential direction. After synthetic resin rod ends are embedded, safety pins 8 are driven in obliquely downwards from the sides of the holes 3 and these safety pins 8 are pierced into the opposite sides of the holes 3 through the resin rods 4 to fix the resin rods 4 to the roll.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new method for planting and fixing resin rods, particularly soft resin rods, onto synthetic resin rolls.

For example, in order to remove the lower leaves of fresh flowers, conventionally, a pair of upper and lower roll brushes are placed facing each other in the axial direction, and these two roll brushes are rotated in opposite directions to remove the lower leaves of freshly cut flowers. I was trying to brush it off.

The roll brush has synthetic resin bristles planted on the outer periphery of a wooden roll.

If you use a lower leaf machine with only a roll brush, you won't be able to remove thorns like roses, and the rolls are made of wood, so if the fresh flowers are wet, the roll lv will expand and contract, causing cracks. The problem was that the hair would fall off.

In order to overcome this drawback, it has been considered that rubber protrusions are integrally formed on the low/I/size surface, but this rubber roll has the disadvantage that the rubber protrusions break off from the base in a short period of time. there were.

As a result of repeated research, we found that by using synthetic resin row/l' for the roll, and planting hair made of hard synthetic resin wire on the outer surface of this roll, as well as planting soft synthetic resin rods, It has been found that all of the above drawbacks can be overcome.

Further, the roll must be lightweight, inexpensive, and easy to process, and polypropylene is the most suitable resin to meet these requirements. However, in the case of polypropylene, adhesives have no effect, so the technology to fix the resin rod to the surface of the roll is extremely difficult, and if a strong force is applied, the resin rod will be pulled out of the roll, making it unusable in reality. was.

The present invention was completed as a result of sufficient consideration of the above-mentioned circumstances.After the end of the resin rod is inserted into the hole formed on the surface of the synthetic resin roll n'31, the end of the resin rod is inserted from the side of the core. A stop needle was driven diagonally downward, and the stop needle was passed through the entire resin rod, and the end of the stop needle was inserted into the opposite side of all the holes to fix the resin rod to the roll. This allowed the resin rod to be glued. This is an excellent method for planting a resin rod onto a resin roll, which securely fixes it to a rod made of any kind of resin and does not fall off even under harsh use.

Below, one embodiment of Himi FIlj will be explained based on the drawings. Fig. 1 is an overall perspective view of a roll brush l for a lower leaf collector, and the outer peripheral surface of the polypropylene cylindrical row/I/2 has an axis. A plurality of rows of planting holes 8 are arranged at regular intervals along the direction.
8... will be provided.

In these plurality of planting holes B, 3..., there is a resin rod group 5 in which soft synthetic resin rods 4, 4... are planted, and hairs 6, 6... in which hard resin wires are tied together. The flocked flocks 7 are formed alternately in the entire circumferential direction.

After the soft synthetic resin rods 4, 4... are fully inserted into the holes 8, 8... as shown in FIGS. 1 and 2, they are inserted diagonally downward from the side of the core. Drive a substantially U-shaped needle 8 toward the hole, pass this peg 8 through the resin rod 4, and then push the tip of the peg 8 into the opposite side of the hole 80 to simultaneously insert the adjacent resin rod 4.4 into the hole. Fixed within s.

In this way, the resin 4 is penetrated by the stopper 8 in the hole 8, and the tip of the stopper 8 is inserted into the opposite side of the hole and fixed, so there is no need for adhesive at all. It will not fall off from Ushi 8 even if the force continues to act on it.

The shape of the peg 8 is not limited to the U-shape, and each resin rod 4,
You can also make it so that each of the 4 VCs can be used all the time.

The roll brush 1 of the present invention constructed by such a method is inserted and fixed, for example, into rotating shafts provided above and below the fresh flower lower leaf I& machine 9.

Although the present invention has been explained in terms of a roll for a fresh flower leaf harvester (example), it has a wide range of applications, and can be used as it is as a roll for a vacuum cleaner.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of the resin n fixed to the entire outer periphery of the roll by the method of the present invention. FIG. 2 is a longitudinal sectional view thereof.
