Description

Lottery ticket destruction device

This creation is about a lottery ticket destroying device, especially a lottery ticket destroying device that can cut lottery tickets into pieces one by one to facilitate the destruction process.

Conventional lottery ticket destruction devices, such as Chinese Patent Application Nos. 84208584, 85204451, and 85203923, all disclose technologies that can cut and destroy lottery tickets, but only use ratchets to cut lottery tickets into three elongated shapes The curled paper strip cannot separate the long series of lottery tickets connected one after another, so after being cut and destroyed, it still has the shape of a long strip curl, resulting in a virtual increase in volume expansion. The greater the degree, and the lottery ticket will automatically fall into a collection tube after being destroyed, but the collection tube can only contain a limited number of destroyed lottery tickets, so the collection tube must be cleaned repeatedly, so not only increases the trouble of destruction, but also greatly reduces The efficiency of destroying lottery tickets.

To this end, the creator of this case has proposed an improved lottery ticket destruction device, such as shown in the Chinese Patent Announcement M554380, which drives a transmission gear set, two guide rollers, and two shear rollers through a motor on one side of the body. Allows the user to insert a long list of lottery tickets from the insertion slot at the top, through the two guide rollers to send the lottery ticket roll between the two shear rollers below, and then through the shear groove structure on the surface of the two shear rollers , Cut the lottery ticket diagonally into pieces and discharge it downward.

However, the two sides of the cutting groove of the two cutting rollers are perpendicular to the surface of the cutting roller, so after the lottery ticket is cut into fragments, it will be stuck in the cutting groove and cannot be discharged smoothly. If too many fragments accumulate, it may also cause The cutting action is not smooth. In addition, the two shear rollers are driven by the two passive wheels of the transmission gear set, so that the cuts of the two shear rollers bite together, no matter whether they rotate forward or reverse, they can not relax the cuts that bite together. Therefore, when accidentally winding two overlapping lottery tickets at the same time, the cuts of the two shear rollers will be stuck by the lottery ticket, which can only be eliminated through a complicated dismantling process. To this end, how to overcome the shortcomings of the above two shear rollers is the subject to be actively overcome for this creation.

The main purpose of this creation is to provide a lottery ticket destruction device, which is provided with two shear rollers in the machine body, and the surface of the two shear rollers are respectively implemented with a plurality of helical shear grooves, each of which is concave The groove on the surface of the shear roller; in particular, the shear groove has a groove bottom surface, one end of the groove bottom surface has a vertical shear surface connected to the surface of the shear roller, and the other end of the groove bottom surface has a row connected to the surface of the shear roller Chip slope; by this, the vertical shear plane of the shear groove through the two shear rollers can cut the lottery ticket into fragments, and the chip discharge slope through the shear groove can avoid the lottery chip stuck in the shear groove and promote Lottery fragments are discharged downward.

The second objective of this creation is to provide a lottery ticket destruction device, which forms a joint part through one end of the rotating shaft of one of the two shearing rollers, and the joint part sequentially sets the second passive gear and an elastic element of the transmission gear set And a detent element; one end of the elastic element abuts the second passive gear and the other end abuts the detent element; thereby, the detent element is pushed by the elastic force of one end of the elastic element, so that the detent element pushes it The vertical shearing surface of the shearing roller is meshed with the vertical shearing surface of the other shearing roller, so the vertical shearing surface where the two shearing rollers are engaged has a predictability of elastic activity, which can prevent two lottery tickets from being involved at the same time. The resulting paper jam condition.
