Abstract

The steel strapping machine without using joint currently available from the market has three shortcomings. Firstly, packages cannot be strapped tightly. Secondly, a steel strap may get caught on a lower mold when the lower mold is taken out from underside of the steel strap. Thirdly, the strapping machine is not available for small packages. To overcome the shortcomings of the prior arts, the present disclosure proposes a separatable lower mold of the steel strapping machine without using a joint, which is formed as two parts being able to be closed together or separated from each other. The separatable lower mold has advantages that packages can be strapped tightly, the steel strap will not get caught on the lower mold when the lower mold is taken out from the underside of the steel strap and it is possible for the strapping machine to strap small packages.

Claims

1. A steel strapping machine without using joint, comprising:

a mold, including an upper mold and a lower mold, which cooperate with each other to shear a steel strap so as to generate a notch, wherein;

the lower mold is formed as a separatable lower mold which is configured to open and close;

the separatable lower mold is closed before a joint is made, and is opened after the joint is made so that the lower mold is removed away from the steel strap,

wherein the steel strapping machine further comprises a base and a feed roller, the feed roller and the mold are mounted on the base, and the base is configured to move up and down and carry the feed roller and the mold to synchronously move up and down,

the lower mold comprises a left part of the lower mold and a right part of the lower mold, which are configured to separate from each other and the left part contacts the right part when the lower mold is closed, and

after the joint is made, the upper mold is moved upwards, the left part of the lower mold and the right part of the lower mold are separated towards two sides of the steel strap in a linear manner and are horizontally taken out from underside of the steel strap.

2. The steel strapping machine without using joint according to claim 1, wherein, each of the left part of the lower mold and the right part of the lower mold is provided with a cutter edge.

3. The steel strapping machine without using joint according to claim 2, wherein, in the state that the left part of the lower mold and the right part of the lower mold are closed together, the cutter edge of the left part of the lower mold and that of the right part of the lower mold keep a certain distance from each other, and cutter edge surfaces of both the cutter edges are disposed towards a center of the steel strap.

4. The steel strapping machine without using joint according to claim 3, wherein, the notch of the steel strap is located between the cutter edge of the left part of the lower mold and that of the right part of the lower mold, after the notch is generated.

5. The steel strapping machine without using joint according to claim 1, wherein, each of the left part of the lower mold and the right part of the lower mold is provided with a blade.

6. The steel strapping machine without using joint according to claim 5, wherein, in the state that the left part of the lower mold and the right part of the lower mold are closed together, cutter edge surface of the blade on the left part of the lower mold and that of the blade on the right part of the lower mold keep a certain distance from each other.

7. The steel strapping machine without using joint according to claim 6, wherein, the cutter edge surface of the blade on the left part of the lower mold and that of the blade on the right part of the lower mold are disposed towards a center of the steel strap.

8. The steel strapping machine without using joint according to claim 6, wherein, the notch of the steel strap is located between the blade on the left part of the lower mold and that on the right part of the lower mold, after the notch is generated.
