Description

Special tools for manual unpacking of banknote packaging plastic boxes

technical field

The utility model relates to the technology of a special manual tool, in particular to a special tool for manual unpacking of a banknote packaging plastic box.

Background technique

The cover of the banknote plastic cash transport box related to the utility model adopts a multi-point disposable locking structure in order to enhance safety. If you want to open the plastic box, you must use the operation of destroying the box cover to remove the box cover, and in order to reduce the cost, it is required that the box body is not damaged and can be recycled. Due to the particularity of the structure and cover of the plastic cash transport box, it is very difficult to open the cover. There is no ready-made tool for removing the cover. Generally, a hammer is used to hit a rectangular punch aligned with the cover lock pin to separate the lock pin from the cover and remove the cover, or use other general tools to destroy the cover. The latch is partially covered. These methods have many disadvantages. First, the process of removing the cover is very time-consuming and laborious; second, although the lock pin is separated from the box cover, it is still stuck in the lock pin hole of the box body and is difficult to remove; third, it often causes damage to the box body and cannot be recycled. use.

Detailed ways

With reference to accompanying drawing 1, banknote packing box unpacking special tool is to comprise four-bar linkage mechanism of pressure head, crank slider mechanism of cutting head, upper handle 1, lower handle 23 and opening spring 18 and constitutes, and described four-bar linkage mechanism of pressure head comprises The upper pressing handle 2, the upper clamp head clip 5, the lower pressing handle 22, and the middle connecting rod 20 are connected in such a way that the upper pressing handle 2 is hinged with the two upper clamp head clips 5 with the pin shaft 4 as the axis, and the pin shaft 4 is used as the axis. The shaft 3 is hinged with the middle connecting rod 20; the two lower pressure handles 22 are hinged with the middle connecting rod 20 with the pin shaft 19 as the shaft, and are hinged with the two upper pliers clips 5 with the pin shaft 6 as the shaft; the upper connection The block 8 is fastened on the left and right two upper pliers clips 5 by fastening screws 7, and the upper cutter head 9 is connected with the upper connecting block 8 by a top screw. The head-cutting crank slider mechanism includes an intermediate connecting rod 20, an oblique push rod 16, a guide groove 15 of a lower pressure handle 22, a lower cutter head 11 and a lower connecting block 13, and the connection mode is that the intermediate connecting rod 20 is connected with a pin shaft 19 The shaft is hinged with the two lower handles 22, and the pin 3 is hinged with the oblique push rod 16; the oblique push rod 16 is hinged with the lower connecting block 13 with the pin shaft 14 as the axis, and the pin shaft 14 can be hinged between the two lower pressure handles. The guide groove 15 on the 22 slides, drives the lower connecting block 13 to reciprocate, and the lower cutter head 11 is fixed on the lower connecting block 13 by a top screw, and moves back and forth with the lower connecting block 13, while the lower supporting block 10 is fastened on the lower pressing block by screws. Put 22. The four-bar linkage mechanism of the pressing head shares the middle connecting rod 20 and the lower pressing handle 22 with the head-cutting crank-slider mechanism. The upper handle 1 is fixedly connected with the upper press handle 2 by screws, and the lower handle 23 is fixedly connected with the lower press handle 22 by screws to provide the power required by the tool. One end of the opening spring 18 is connected to the lower handle 22 through the pin 17 , and the other end is connected to the intermediate link 20 through the pin 21 .

Fig. 1 is the fully pressed position of the special tool. The tool as a whole is a multi-link mechanism (double four-bar linkage mechanism), wherein the upper pressing handle 2, the upper pincer clip 5, the lower pressing handle 22, and the middle connecting rod 20 constitute a four-bar linkage mechanism; the middle connecting rod 20, The inclined push rod 16, the guide groove 15 and the lower cutter head 11 and the lower connecting block 13 of pressing down the handle 22 constitute another deformed four-bar mechanism (slider crank mechanism).

The action process of the special tool from the pressing position to the opening position is: the middle connecting rod 20 drives the upper pressing handle 2 to rotate under the pull of the opening spring 18, thereby driving the upper clamp head clip 5 to rotate around the pin shaft 6, The tool jaws are opened thereupon, and the intermediate connecting rod 20 moves around the pin shaft 19, pulling the inclined push rod 16, so that the pin shaft 14 drives the lower cutter head 11 to move in the guide groove 15, and pulls the lower cutter head 11 to move backward.

The action process of the working stroke of the special tool is: pressing the upper handle 1 drives the lower pressing handle 2 to rotate counterclockwise, and the pin 4 drives the upper jaw clip 5 to rotate around the pin 6, thereby driving the upper cutter head 9 downward Movement; at the same time, press down the handle 2 to push the oblique push rod 16 down to the left through the pin shaft 3, so that the pin shaft 14 drives the lower cutter head 11 to move forward in the guide groove 15. Reasonable design of the length of each connecting rod can make the upper cutter head 9 move faster downward when the first half of the stroke of the upper handle 1 is pressed, while the lower cutter head 11 moves forward slowly. When the upper cutter head 9 moves to When the stroke is set, the lower cutter head 11 starts the working stroke to cut off the lock pin punched down by the upper cutter head 9, thereby realizing that the lid lock pin is punched down by the upper cutter head 9 in one stroke of pressing the upper handle 1 Two actions that are cut off by lower cutter head 11 again afterward.

The distance from the pin shaft 6 to the pin shaft 4 of the special tool is greater than the distance from the pin shaft 6 to the upper cutter head 9, and the distance from the pin shaft 3 to the force point at the grip of the upper pressing handle 2 is far greater than that from the The distance from bearing pin 3 to bearing pin 4, two lever mechanisms are labor-saving mechanisms. The combination of these two labor-saving mechanisms makes the special tool have labor-saving characteristics.
