Concept ideas and first CAD
Published 1yPublished almost 2 years ago
Soo, the wood splitter project continues. The first step was to collect ideas on an online whiteboard and back up the initial keywords with small sketches. ......Crushing large plastic objects (Crusher), producing pressed parts from alternative materials such as coffee grounds (OrganicPress), pressing small sheets (SheetPress), producing injection molded parts (Injection), tapping into the oil circuit for additional peripheral devices and, of course, making everything run as automatically as possible..... A few topics.
Ideas are all well and good, but they have to be practicable and easy to implement. A perfect time to create the first CAD models. If you bring the different approaches together virtually, different interchangeable inserts are available for the pressing tasks. A quick glance at the safety officer also reveals that heat, pinch points and automatic drains..... better to pack everything in a closed housing. The project roadmap for the next few weeks is now complete.

Step 2: Housing
Published 1y. Edited 1yPublished almost 2 years ago. Last edit almost 2 years ago
The work continues on the enclosure. As you naturally want to see what the machine is doing, old Corona protective screens from a company donation were used for the cladding in the upper area. Below this, self-made panels made from recycled material are used, giving 10 kg of plastic waste a new purpose. To access the work area, the front screen can be moved in old roller shutter guides and holds its position thanks to a weight compensation system made from old project materials. As you can see, this is a real upcycling project in which everything that's lying around in the workshop is used. The change system was also tinkered with. The splitting slide itself has been retained, but the splitting wedge has been nicely removed. Two welded-on struts now allow different inserts to be inserted flexibly. In the next round, the electronics and the first shredding insert will slowly be added.

Crusher Test
Published 1yPublished almost 2 years ago
The first insert for the change system will be the crusher. This is a metal geometry for pre-shredding bulky plastic parts that would otherwise not fit into the shredder. A solid aluminum plate with a welded base serves as a counter bearing for the first steps. Various blade geometries can be tested against the material to be shredded on this plate in order to finally cast the final insert from the experience gained. Good that there is still enough metal material in the workshop to play around with. The base frame for the table is made from old rectangular tubes and steel plates from the first furnace molds served as the base material for the insert.

Crusher Final
Published 1yPublished over 1 year ago
As we remember, the crusher insert is designed to help shred bulky plastic parts that would otherwise not fit into the shredder. In initial tests, a splitting knife mounted on the carriage disintegrated its plastic counterpart.
This worked so far, but always required precise positioning. Therefore, the general concept for the final version required a significant adjustment. So why not install the whole setup in reverse? The knives are arranged in a grid in the table frame. The solid table top itself serves as a pressing stamp in this scenario. To set up the crusher, it is therefore sufficient to hook an adapter into the carriage and screw it to the table top. After that, the machine does what would otherwise have to be done by hand in laborious, rough work. Nice.
