Abstract
In social, economic and ecological terms bamboo is one of the non-timber forest products of the developing countries, especially
in Asia. Therefore numerous technologies being developed for the processing of the bamboo for the production of several bamboo
products .Some of these technologies have remained unmodified over long periods of time, while others have seen alterations to suit
changing requirements.
The traditional processes which are carried out on six different machines from cutting of bamboo, splitting ,knot removing, slicing,
stick length setting, and polishing. For all this lot of time consumed, cost increases as different machines used, labour cost increases
etc.
Now we are trying to minimize all these processes in a single machine, less labour cost, less time, and increasing desired output at low
cost.
KEYWORDS: Stick length setting, Cutting of bamboo, splitting, knot removing, slicing, polishing
1. INTRODUCTION
Initial treatment to raw bamboo before ready for actual work is called bamboo processing which includes
cutting ,splitting, external and internal knot removing, stick length setting etc .Bamboo and Bamboo splits are used as
fencing material and for making various types of tool handles ,ladders and scaff holding. Splits as well as slivers are used to
make a wide range of product such as basket, the core of incense sticks, kites and toys, flutes and large number of handicraft
items. it is also used to make cage for poultry, drying, packaging and transport of grains. Bamboo splits are woven into mats
and use to manufacture mat boards.

2. OBJECTIVES
Presently for all processing of bamboo, individual machines are available. The main theme involved in this
work is to design and fabricate a machine with especially of multiple operation of bamboo processing in a single machine.
The design involves a new concept of bamboo processing machine with multiple operations with help of multipurpose die.
3. Traditional details of bamboo processing machine.
3.1 Cross Cutting Machine:
The cross cutting of bamboo includes the cutting of bamboo into required size so that it can fit into
splitting machines .This is done due to the varying sizes of bamboo.

3.2 Splitting Machine:
This machine is used for splitting of bamboo into number of equal parts it depends upon the module of die it
might of four or six equal parts and so on…

THE MAIN FOCUSES ON DIE, TO TAKE VARIETITIES OF DESIRED PRODUCT LIKE INSENSE STICS, ICE
CREAM STICS. SO WE NEED TO DEVELOPE TYPES OF DIE FOR DESIRED PRODUCT.
5. FOCUS ON MULTIPURPOSE DIE
5.1 INTRODUCTION
Die is the machining element which is one of the most important and essential element in the field of
bamboo processing machine. Die is used to break down the bamboo (raw material) and convert it into finish product such as
tooth pick, ice-cream etc.
5.2. CONSTRUCTION
Die is made of three tool plates which are placed inside the single housing. This plates are kept as one by one
inside the housing so that right from splitting to the end of finish product can be achieved.
1)
HOUSING:It’s one of the robust hollow shaped bar. We have to place it outside the tool plates which covers & gives
support to the plates. This housing is fixed to the machine below the actuator in certain distance. After that introduce plates
one by one in reverse sequence which makes a complete die.
Fig. 5.2.1
2) FIRST TOOL PLATE:There are 8 cutting tools are arranged vertically in an angle and welded to the middle spindle as well as the
plate. These cutting tools are used to cut/ split the bamboo in 8 equal parts vertically and then allow to feed to the next tool
plate.

BACK
Fig 5.2.2
3) SECOND TOOL PLATE:In this 5 tools are arranged horizontally like steps in 1/8th part of the circle. This tool will cut the bamboo in
slicing (means thickness is far less than the width) and then allow feed to the last tool plate.

FUTURE SCOPE
 To increase the bamboo cutting length, we have to increase the actuator length and increase spacing between plunger and
die housing.
 To increase the applied pressure, we can simply increase the fluid flow using direction control valve.
 As per product requirement we can use various types of tool plates. Such as, for ice cream sticks we use two tool plates and
for incense sticks making we use three tool plates.
 According to the diameter of bamboo, we can change the diameter of die and thus housing.
 If we increase the diameter of die hence we have to increase distance form frame to centre of die as well as centre of the
actuator.
 By providing the polish bath instead of collector, we direct get the polished product.
