Description

[Detailed explanation of the idea] Industrial applications The present invention relates to cane mills.

Conventional technology A conventional cane mill has a bottom roll and a bagasse roll installed in parallel at the bottom of the housing, a top roll installed parallel to both rolls at the top of the housing, and a feeder roll fixedly installed at the top of the housing parallel to the top roll. It was configured.

Problems to be solved by the invention According to the above conventional configuration, the feeder roll was used only to facilitate the supply of cane to the three-roll cane mill, but since it is a fixed type, it cannot be used as a feeder roll. The cane that is supplied between the top rolls with uneven layer thickness cannot be compressed uniformly over the entire length in the width direction of the feeder roll, which is a problem when feeding the cane to the three-roll cane mill. Moreover, since the squeezing force is small, usually 10 to 20 ToN, it has been impossible to extract dieuse from cane.

The present invention solves the above problems,
To provide a three-roll press feeder roll cane mill capable of uniform and constant pre-compression of cane and preliminary extraction of juice.

Means for Solving the Problems In order to solve the problems, the present invention provides a lower housing that supports the bottom roll and the bagasse roll in parallel, and the cane supply side of the upper housing that supports the top roll parallel to both rolls. A press feeder roll is arranged parallel to the top roll, and one end of a swing arm that supports both shaft ends of the press feeder roll via spherical bearings is swingably attached to the upper housing via a pin, and A cylinder device is provided between the other end of both swing arms and the lower housing via a pin, respectively.

Operation In the above configuration, the cylinder device is operated according to the layer thickness (amount) of the cane between the top roll and the press feeder roll to move the press feeder roll toward and away from the top roll. At this time, since the press feeder roll is supported by the swing arm via a spherical bearing, the distance from the top roll to the top roll can be adjusted independently at both ends of the press feeder roll, and the entire length in the width direction of the press feeder roll can be adjusted independently. Cane pre-squeezing can be performed relatively uniformly across the cane and juice pre-extraction can be performed.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

In FIG. 1, numeral 1 denotes a lower housing that supports a bottom roll 2 and a bagasse roll 3 in parallel via bearings 4 and 5, and supports a bottle roll 2 at a slightly lower position than the bagasse roll 3. Reference numeral 6 denotes an upper housing which supports a top roll 7 parallel to both rolls 2 and 3 so as to be freely raised and lowered, and the lower ends of both sides of the lower housing 1 are arranged between both rolls 2 and 3 through pins (pin joints) 8 so as to be able to swing freely. connected. Reference numeral 9 denotes two first hydraulic cylinder devices installed on both sides of the upper housing 6, which hold down both shaft ends of the top roll 7 via bearings 10 that are movable up and down with respect to the upper housing 6. It functions to urge the top roll 7 downward as appropriate. A swing arm 11 is swingably attached to both sides of the cane supply side of the upper housing 6 via a pin 12, and supports both shaft ends of a press feeder roll 13 parallel to the top roll 7 via a spherical bearing 14. are doing. Reference numeral 15 denotes a bracket protruding from both sides of the cane supply side of the lower housing 1, and reference numeral 16 denotes two second hydraulics installed between the bracket 15 and the lower ends of both swing arms 11 via pins 17 and 18. With a cylinder device,
It functions to move the press feeder roll 13 toward and away from the top roll 7 by swinging the swing arm 11.

The operation of the above configuration will be described below. A cane is fed between the press feeder roll 13 and the top roll 7, and an appropriate amount of the press feeder roll 13 is fed to the top roll 7 using the second hydraulic cylinder device 16.
bias to the side. Since the press feeder roll 13 is supported by the swing arm 11 via a spherical bearing 14, the distance from the top roll 7 can be maintained independently at both ends of the press feeder roll depending on the layer thickness of the cane to be fed. Then, the cane is pre-pressed relatively uniformly over the entire length in the width direction of the press feeder roll 13, and the juice is pre-extracted. Next, the cane is fed between the bottom roll 2 and the top roll 3. At this time, by urging the top roll 7 downward by the first hydraulic cylinder device 9, the gap between the top roll 7 and the bottom roll 2 and between the top roll 7 and the bagasse roll 3 is increased.
Adjust the squeezing force between. At this time, the pressurizing force of the second hydraulic cylinder device 16 is transmitted to the top roll 7 via the press feeder roll 13, and then becomes part of the squeezing force between the top roll 7 and the bagasse roll 3. The cane that has been pressed and extracted from youth is extracted from between top roll 7 and bagasse roll 3.

Effects of the invention As described above, according to the invention, it is possible to always perform uniform and constant pre-squeezing and preliminary extraction of juice against changes in layer thickness in the cane flow direction and in the width direction of the press feeder roll. Enables forced and efficient cane feeding to the 3-roll cane mill. Therefore, the squeezing performance per cane mill is improved.
