1. Field of the Invention
The present invention relates to a breaking machine, and more particularly to an auto-breaking machine.
2. The Related Art
Traditionally, a plurality of metal shells is connected on a base band before being used to facilitate the storage. In use, the metal shells are broken off the base band by hand. However, breaking the metal shells off the base band by hand suffers from low work efficiency and also unnecessarily wastes a great deal of manpower. Furthermore, the metal shells are apt to injure hands of operators because of a great deal of burrs formed around the metal shells. Therefore, an auto-breaking machine which overcomes aforementioned problems and is capable of automatically breaking the metal shells off the base band is required.
An object of the present invention is to provide an auto-breaking machine adapted for breaking metal shells off a base band. The auto-breaking machine includes a frame assembly, a first breaking assembly, a power assembly and a turntable. The first breaking assembly has a support assembly disposed on the frame assembly, a first breaking member and a second breaking member pivoted on the support assembly and spaced away from each other for allowing the base band passing therebetween. The second breaking member has a breaking portion at a free end thereof and keeps a distance from a free end of the first breaking member for breaking the metal shells off the base band. The power assembly is disposed on the frame assembly. The turntable is rotatably mounted to the power assembly and driven by the power assembly for driving the base band to move.
As described above, the auto-breaking machine can break the metal shells off the base band automatically by way of the breaking portion acting the pressure on the metal shells during the base band moving. Therefore, the auto-breaking machine can improve work efficiency and save a great deal of manpower.
The present invention will be apparent to those skilled in the art by reading the following description of a preferred embodiment thereof, with reference to the attached drawings, in which:

The frame assembly 1 further includes a first preventing board 140, a second preventing board 141, a third preventing board 142 and a fourth preventing board 143 which are rectangular. The first preventing board 140 and the second preventing board 141 are vertically fixed on a right of the first padding board 111 facing each other. The first preventing board 140 lies in a left of the second preventing board 141 and abuts against a right end of the support board 15. The first preventing board 140 defines a first fixing window 1401 transversely passing therethrough and a right end of the feeding assembly 4 is inserted in the first fixing window 1401. The second preventing board 141 defines a second fixing window 1411 facing to the first fixing window 1401 and a connecting perforation 1412 at front extending rearward to communicate with the second fixing window 1411. The fourth preventing board 143 is fixed on the front of the first preventing board 140 and the second preventing board 141 at top. The third preventing board 142 is horizontally fixed on the first preventing board 140, the second preventing board 141 and the fourth preventing board 143. A guiding block 13 is fixed on the first padding board 111 between the first preventing board 140 and the second preventing board 141. Two sides of the guiding block 13 respectively abut against the first preventing board 140 and the second preventing board 141. A top surface 131 of the guiding block 13 gradually inclines downward from rear to front.

The first breaking member 25 has a cylindrical first base portion 251, a first pivoting portion 252 extending rearward from a middle of the first base portion 251, and a guiding portion 253 extending forward from the first base portion 251 and gradually shortening in diameter. The first pivoting portion 252 is pivoted in the first locating hole 211 and the first base portion 251 is located above the guiding block 13. The second breaking member 26 has a cylindrical second base portion 261, a second pivoting portion 262 extending rearward from a middle of the second base portion 261, and a breaking portion 263. The second pivoting portion 262 is pivoted in the second locating hole 221, and the second base portion 261 lies above the first base portion 251 and is apart from the first base portion 251. The breaking portion 263 is fixed on a front of the second base portion 261 and diameters thereof are gradually increased from rear to front. The breaking portion 263 is apart from a front of the guiding portion 253.
The second breaking assembly 3 includes a rectangular assistant body 31, a preventing block 32 and an adjusting pin 33. The assistant body 31 is fixed in the second fixing window 1411 and defines a receiving window 311 passing through a front and two sides thereof. The preventing block 32 is movably received in the receiving window 311 and defines a receiving fillister 321 at front. A rear end of the adjusting pin 33 passes through the connecting perforation 1412 to be screwed into the receiving fillister 321, whereby the preventing block 32 can be adjusted to move forward or rearward in the receiving window 311 by way of turning around the adjusting pin 33.

As described above, the auto-breaking machine of the present invention can break the metal shells 81 off the base band 8 automatically by way of the breaking portion 263 acting the pressure on the metal shells 81 during the base band 8 moving. Therefore, the auto-breaking machine can improve work efficiency and save a great deal of manpower.
