Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, a scrap recycling and crushing device for a TPU film comprises a roller 1, a trimming knife 3 is arranged on one side of the roller 1, an installation box 5 is arranged in the discharging direction of the roller 1, the trimming knife 3 and the installation box 5 are connected with a frame or other structures of a whole production line, the specific structure is not repeated, and the respective effect can be realized, a feed inlet is formed in the top of the installation box 5, and the feed inlet corresponds to the falling position of a trimming material 2, so that the cut scrap just falls into the feed inlet; the bottom of the mounting box 5 is provided with a discharge hole for discharging the trimming materials 2 cut into small pieces; and specific crushing structure is that the inner wall of install bin 5 rotates and is connected with baffle 8, common fixedly connected with spring 7 between baffle 8 and the install bin 5, the effort direction of this spring 7 is all the time for the direction that promotes baffle 8 to cutting off cutter 11, install bin 5's inside still rotates and is provided with connecting roller 10, connecting roller 10 rotates through the inner wall of pivot with install bin 5 and is connected, install bin 5's outer wall fixedly connected with motor 6, the output shaft and the pivot fixed connection of motor 6, it rotates to drive connecting roller 10 automatically through motor 6, the even fixedly connected with cutting off cutter 11 of lateral wall of connecting roller 10, the cutting part and the baffle 8 of cutting off cutter 11 offset, further strengthen the effort of abutting tightly through the effect of spring 7, so that cut off offcut 2 better.

In the specific embodiment, the baffle 8 in the installation box 5 is arranged in an inclined manner, so that the trimming material 2 can move along the baffle 8, and the inclined angle corresponds to the rotating position of the cutting knife 11, so that the cutting knife 11 is vertically or slightly inclined on the baffle 8, and the trimming material 2 can be cut off better; further, the edge part roll connection of roller 1 has compression roller 4, and compression roller 4 staggers with the main part film, only extrudees side cut material 2, and concrete connection structure is not giving unnecessary, and fixedly connected with deflector 9 is still gone back at the interior top of install bin 5, and the bottom of deflector 9 is corresponding with baffle 8, sets up through above-mentioned structure for in the side cut material 2 can get into install bin 5 smoothly, and can slide along baffle 8, and can not get into other positions.

It is worth mentioning that this rim charge breaker can set up one side or both sides at the production line according to the actual requirement of cutting edge, and this embodiment has only exemplified one side and has set up and explain, and the device can the direct mount near the conveying roller position of former production line, and compact structure is small and exquisite, can not occupy too much factory building space.

The working principle is as follows: when using, the offcut 2 passes through in the compression roller 4 gets into install bin 5, this moment offcut 2 falls on baffle 8 along deflector 9, and slide along baffle 8, motor 6 starts this moment, drive a plurality of cutting off knives 11 constantly rotatory, make one of them certain cutting off knife 11 and baffle 8 contact, just so make cutting off knife 11 cut the offcut 2, along with cutting off knife 11 constantly rotatory, with long banding side cut 2 of cutting off, fall out in the discharge gate at last, the collecting box that prepares in advance is placed to the below and is collected.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
