Present invention provides a mass shaped detaching razor device, which allows detaching the mass shapes from the laminating roller without damaging the same, in such a way that if an imperfection should occur in said device, it would only be necessary to remove one specific razor device, not being necessary to stop the functioning of the laminating rollers.
The concept of a razor device was born from the need of eliminating setbacks which the use of metallic threads for removing the product from the laminators entails.
We have knowledge of U.S. Pat. No. 4,966,541 dated Oct. 30, 1990 which describes a wire detachment adjustor for laminating rollers which present mass in laminated shapes formed between a pair of roller and separated from a roller by the detachment wire subject to tension by means of guides set in order to align the detachment wire with end peripheries opposite to the roller, which present an infinity of variable positions.
Similarly, we also have knowledge of U.S. Pat. No. 8,679,563 B1 dated Mar. 25, 2015 which refers to a laminator which presents a frontal roller without an inner groove, a back roller configured to rotate in the opposite direction from the frontal roller, a detachment wire partially spiral coupled through the frontal roller and a conveyor band connected to a proximal conveyor roller and a distal conveyor roller.
Metallic threads, although efficient, have the disadvantage of easily becoming damaged if they are not used in the correct manner, which has as a consequence the complete shutdown of the production line in order to make a substitution.
Present device completely replaces the metallic thread, improving the yield of the laminating equipment.

Additionally, present invention refers to a detachment razor system which comprises a right lateral support and a left lateral support, a support bar coupled on the upper ends of said lateral supports and between the same, a pivot bar coupled between said lateral supports, underneath the support bar, and at least one mass shaped detaching razor device which comprises a main support, which is found coupled by its upper section to a lower end of a pressing arm by means of a pivot coupling, the main support is coupled by its lower section to a razor support, the razor support presents in a frontal end a detachment razor, a shock absorber coupled by its lower end with a back end of the main support and coupled by its upper end to an upper end of the pressing arm, said razor device is found coupled unto the pivot bar by the first pivot coupling.

The following description makes references to
The mass shaped detaching razor device (1) of present invention comprises a main support (10), which presents a lower section (11), an upper section (12), a frontal section (13) and a back section (14), the upper section (12) has a circular opening (15) in which a bushing (16) is coupled unto and a securing collar (17), while the back section (14) presents at least two perforations (18), which have the same diameter but are at different heights; similarly, the lower section (11) is smooth.
Said main support (10) is found coupled by its upper section (12) with a lower section (21) of a pressing arm (20), it should be noted that said lower section (21) presents a circular opening (25), which is coincident with the circular opening (15) of the upper section (12) of said main support, likewise said pressing arm (20) also presents an upper section (22), a frontal face (23) and at least one lateral face (24); said coupling between the main support (10) and the pressing arm (20) corresponds to a first pivot coupling, similarly it also presents a second pivot coupling on said at least one lateral face (24), said second pivot coupling being set above the first pivot coupling.
Said main support (10) is found coupled by its lower section (11) unto a razor support (30), wherein the razor support (30) comprises a fixed support (31) as well as a guided support (32), wherein the guided support (32) is found in slidable coupling with the fixed support (31) by means of a pair of longitudinal flanges (33), which are arranged at the lateral ends of the guided support (32), which are coupled to the lateral ends of the fixed support (31).
The guiding support (32) has a frontal section (36) and a back section (37), on said frontal section (36) a razor (40) is removably coupled, below said razor (40) a lower support (38) is found, which holds the razor (40) coupled unto the guided support (32). It should be mentioned that the razor (40) may present shape and size modifications, which do not deviate from the scope of the invention.
Set between the back section (14) of the main support (10) and the upper section (22) of the pressing arm (20) is a gas shock absorber (50), in such a way that a lower section (51) of the gas shock absorber (50) is found coupled with the back section (14) of the main support (10), and an upper section (52) of the gas shock absorber (50) is found coupled with the upper section (22) of the pressing arm (20); the lower section (51) of the gas shock absorber (50) is coupled into one of said at least two perforations (18) of the back section (14) of the main support (10).
The gas shock absorber (50) modifies the inclination of the main support (10) with regard to the pressing arm (20), in such a way that when said shock absorber (50) is found in a retracted position, the main support (10), presents a first inclination and when the gas shock absorber (50) is in an expanded position, the main support (10) presents a second inclination, the first inclination being different from the second inclination.
In said second pivot coupling, a pressure lever (60) is coupled, which presents a distal end (61), a proximal end (62) and two longitudinal sections perpendicular to each other attached at a vertex, in such a way that said pressure lever (60) partially wraps the pressing arm (20), found between the pressing arm (20) and the pressure lever (60), a pressure spring (65) is found, which is perpendicular to the second pivot coupling, so that it is located on the frontal face (23) of the pressing arm (20); similarly, the proximal end (62) of the pressure lever (60) has a toothed border edge (66) which is coupled to a plurality of teeth (71) of a brake wheel (70) set on a side of said first pivot coupling.
The mass shaped razor detachment device (1) of present invention may be installed together with other similar devices in order to form a detachment razor system (100), said detachment razor system (100) presents a right lateral support (110), a left lateral support (120), a support bar (130) coupled at the upper ends (111, 121) of said lateral supports (110, 120) and between them, a pivot bar (140) coupled between said lateral supports (110, 120), below the support bar (130), said pivot bar is coupled unto the first pivot coupling of said mass-shaped razor detachment devices (1).
