Abstract

PROBLEM TO BE SOLVED: To maintain the relative positions of a sliding roller and a scraper constantly appropriately and perform adequate stripping and cleaning of deposits on the outer peripheral face of the sliding roller by providing a scraper holding part on the bearing of the sliding roller, in a roller device which performs a crushing or a rolling process with a stationary rotating roller and a sliding roller. SOLUTION: A bearing 2 for supporting the shaft 1a of a sliding roller 1 is fitted into a guide 4 provided in a device body 3 and also a spring 6 is interposed between the bearing 2 and a spring receiver 5a of a threaded rod for adjustment to elastically support the bearing 2 and at the same time, a handle 7 is fixed to the outer end part of the threaded rod 5. Further, a scraper 9 is pivotally supported by a support shaft 10 in a bracket 8 arranged at the lower part of the bearing 2, and a pulling spring 11 is tensely insetted between the tip part 9c of the scraper 9 and the stopper pin 12 of the bracket 8. Consequently, the tip 9b of the scraper 9 is urged so that the tip 9b is constantly set in contact with the circumferential face of the sliding roller 1. Thus it is possible to ensure the constantly optimal contact state of the scraper 9 and also make sure that deposits are stripped and removed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller device in which a holding portion of a scraper is moved in conjunction with the sliding of a sliding roller so that the relative contact position of the scraper with the sliding roller remains unchanged. For the scraper device.

[0002]

2. Description of the Related Art In a conventional powder mill, powder is milled by a pair of roller devices consisting of a fixed-position rotating roller and a sliding roller, and the gap between both rollers is adjusted by sliding of the sliding roller. A scraper is in contact with the outer peripheral surface of each of the rollers, and the processing object adhered to the outer peripheral surface of each of the rollers is peeled off. In adjusting the distance between the two rollers, a difference in sliding amount between the left and right ends of the sliding roller is inevitable. As a result, there was a variation in milling particle size or disturbance in the pressing action.

[0003]

In the conventional roller device, since the scraper is rotatably fixed to the machine frame, the outer peripheral surface of each roller and the tip of the scraper are always in elastic contact with each other. However, in the case of the sliding roller, even if the sliding roller slides, the position of the scraper does not change, so that the contact position is necessarily shifted. Since the outer peripheral surface of the sliding roller in the above is cylindrical, if the contact position with the scraper shifts, the contact state changes, and the peeling of the crushed material or the like adhered to the outer peripheral surface of the sliding roller becomes insufficient. There was a point. For example, there is a possibility that a wedge-shaped minute gap may be formed between the outer peripheral surface of the sliding roller and the contact surface of the scraper, and therefore, there is a possibility that the outer peripheral surface of the sliding roller may be insufficiently peeled and cleaned.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problems, and has a structure in which a scraper is held on a bearing of a sliding roller to determine the relative position of the sliding roller and the scraper. Thus, the sliding roller can be slid while always maintaining the correctness.
