[0002] In the existing internal vibration type hollow cement board molding machine, the vibration force of the vibration tube is generated by setting the eccentric fast on the vibration axis. Since the length of the prefabricated slab is generally relatively long, in order to obtain a more uniform vibration, the vibration force is set on the vibration axis. Multiple eccentric blocks, this type of drawing machine is called a multi-point internal vibration type film drawing machine. Although multiple eccentric blocks are set on the vibrating shaft, the distribution of the vibration force is still not uniform, and the hollow cement produced Board quality is not ideal

Embodiment Construction
[0005] The present invention will be described in detail with reference to the above drawings. In order to overcome the uneven vibration force caused by the eccentric block provided on the existing vibrating shaft, an eccentric shaft 3 is welded on one side of the vibrating shaft 2 between the two vibrating sleeves 1. The length of the eccentric shaft is the same as the length of the vibrating shaft. Due to the long length of the hollow cement board, the existing vibrating shaft is a solid long cylinder, which is poor in manufacturability and high manufacturing cost. The vibrating shaft is made into a multi-section vibration tube, and one is placed between the two vibration tubes. Mandrel 4, the end of the vibration tube has two radial holes opposite to the two radial holes of the end of the mandrel, the two vibration tubes are connected into one body by four pins, and the mandrel and the vibration tube hole are slidingly matched , The length of the vibration tube is equal to the ...

The invention discloses a vibrating shaft of an internal vibrating type hollow concrete slab drawing die forming machine, relating to a precast slab forming machine. The purpose of the invention is to provide the vibrating shaft of the internal vibrating type hollow concrete slab drawing die forming machine with uniform vibrating force, a hollow concrete slab manufactured by which has high quality. The technical proposal of the invention is that the vibrating shaft of the internal vibrating type hollow concrete slab drawing die forming machine comprises an eccentric block and a vibrating sleeve; wherein, the eccentric block is a long eccentric body which is fixed on one side of the vibrating shaft; the vibrating shaft comprises a multisection vibration pipe and a mandrel, the two ends of which are respectively matched in the neighboring vibration pipe in a sliding way; a pinion is tightly matched in the radial hole of the vibration pipe and the mandrel. The anti-collision device is used for the precast slab drawing die forming machine.
Description
Technical field: [0001] The invention relates to a prefabricated board forming machine, in particular to a vibration shaft of an internal vibration type hollow cement board drawing machine. Background technique: [0002] In the existing internal vibration type hollow cement board forming machine, the vibration force of the vibration tube is quickly generated by the eccentricity of the vibration axis. Since the length of the prefabricated plate is generally relatively long, in order to obtain more uniform vibration, the vibration axis is installed Multiple eccentric blocks, this kind of drawing machine is called a multi-point internal vibration type stretch film forming machine. Although multiple eccentric blocks are set on the vibrating shaft, the distribution of vibration force is still not uniform. The hollow cement produced The quality of the board is not ideal. Summary of the invention: [0003] The purpose of the present invention is to provide a vibration shaft of an inter...
