Example 15
The die cutting device is adopted, and the method for processing the manual tearing position of the release paper specifically comprises the following steps:
1) mounting an existing semi-finished product 18 to be processed on said plate 16;
2) the driving mechanism 14 drives the flat plate 16 to drive the semi-finished product 18 to be processed to move along the side line direction of the flat plate 16 so as to feed the semi-finished product 18 to be processed, and meanwhile, the machine table 11 drives the tool apron 12 and the die 4 to perform die cutting and punching, so that automatic feeding can be performed to perform die cutting and punching, and a (straight strip-shaped) finished product with upper and lower hand tearing positions is obtained.
Example 16
Compared with the embodiment 15, in the processing method for the manual tear position of the release paper, when the to-be-processed semi-finished product 18 is installed, the to-be-processed semi-finished product 18 is further torn off from the upper release film 1 at one end corresponding to the second cutter 20, and is folded to a position where the mold 4 can be die-cut to form the second manual tear position 6 (specifically, the second notch 8), specifically referring to fig. 8, where fig. 8 schematically illustrates a schematic view of tearing off the upper release film in the manual tear position processing of the release paper according to an embodiment of the present invention.
Example 17
A method for processing a manual tear position of release paper, which uses a die cutting device shown in embodiment 11, wherein a die 4 in the die cutting device is shown in embodiment 10, and the method specifically includes the following steps:
1) mounting an existing semi-finished product 18 to be processed on said plate 16;
2) the driving mechanism 14 drives the flat plate 16 to drive the semi-finished product 18 to be processed to move along the side line direction of the flat plate 16 so as to feed the semi-finished product 18 to be processed, and meanwhile, the machine table 11 drives the tool apron 12 and the die 4 to perform die cutting and punching, so that automatic feeding can be performed to perform die cutting and punching, and a (straight strip-shaped) finished product with upper and lower hand tearing positions is obtained.
In the embodiment of the invention, when the die 4 is used, the width of a finished product with upper and lower hand tearing positions is used as a skip distance for die cutting and three-vehicle forming, and if the material is convenient and saved, the semi-finished product 18 to be processed can be formed after being punched twice in an empty vehicle. Due to the arrangement of the discharge opening 21, waste can be directly discharged from the machine 11 without manually removing waste.
It should be noted that, in the existing hand-tearing position processing method for the semi-finished product 18, multiple stamping and circular die cutting are used for forming, and the processing technology for the upper and lower hand-tearing positions is complex, time-consuming and low in productivity. For example, the processing method of the "one-to-ten" hand tearing position is that the processing die is designed to be A, B two sets of dies, the a die is a left hand tearing position forming knife die, and is provided with four positioning holes and a left hand tearing position knife, the B die is a right hand tearing position forming knife die, and comprises an outer knife and a right hand tearing position knife, the outer knife is provided with four positioning pins for positioning, the processing method of the "one-to-ten" hand tearing position is that the semi-finished product 18 is cut into a required size, then the left hand tearing position (namely, the first hand tearing position 5) is punched through the a die and is punched with the positioning holes, and then the right hand tearing position (namely, the second hand tearing position 6) is punched through the B die, generally, the manual discharging punching man-hour is 500 minutes per hour, the punching is performed twice per die ten holes, and the corresponding punching productivity is 2500pcs/h, wherein pcs (photos) represents the meaning of individual articles.
The invention has the advantages that the processing method of the release paper hand tearing position in the embodiment of the invention only needs to arrange one external dimension knife 13 on one mould 4, and the mould opening cost is ten times as much as that of one knife adopted in the embodiment of the invention because the external dimension knife is required to be arranged into ten knives in the 'one-out-ten' hand tearing position processing method; the embodiment of the invention uses a flat knife die cutting mode, only needs to flatly place materials such as a semi-finished product 18 on a flat plate 16, sets jump distance and tears a release film on the folding side for punch forming, achieves the best material utilization effect by waste materials without space, does not need to sleeve and punch or open a plurality of groups of knife dies for preparing a final finished product for a plurality of times, can reduce cost and improve productivity, has the feeding and taking working hours of 1.5pcs per second during punching, has the average productivity of about 5000pcs/h, has the productivity doubled as that of the original traditional method, effectively improves productivity, reduces cost of the die, and has wide market prospect.
The electric appliances presented in the article can be connected with an external main controller and 220V mains supply, and the main controller can be a conventional known device controlled by a computer and the like.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
