Among the left and right brackets, one is fixed on the machine base, and the other is slidably installed on the machine base.

An upper swing shaft located above the centerlines of the two top shaft holes and parallel to the lower swing shaft is also arranged between the left and right brackets, and the upper swing drive device installed on the bracket is connected with the upper swing shaft; At least two toggle levers are fixed on the top.

The positive effects of the utility model are: (1), the paper tubes to be cut fall into the wheel grooves of the sheave one by one from the feeding device, and the left and right top shafts move inwardly through the two top shaft holes at the same time, and are respectively inserted Both ends of the paper tube rotate with the paper tube; the cutting knife enters the knife and rotates passively with the paper tube, cutting both ends at the same time. After cutting the head, the left and right top shafts move outward at the same time, taking away the paper tube head; the lower swing shaft drives the groove wheel to rotate at a certain angle to realize the swing and transposition of the wheel groove, and then sends out the paper tube after cutting the head, and then swings back immediately Accepts falling paper tubes in situ. The above actions are repeated to realize the automatic operation of the paper tube cutting head. Production efficiency is increased by more than 100% compared with traditional equipment. (2) The support on at least one side can be moved, and the processing size (the length of the paper tube to be cut) can be adjusted adaptively. (3) There are at least two toggle levers on the upper swing shaft. The paper tubes falling from the feeding device are held by the toggle levers. The toggle lever swings once and puts down a paper tube to ensure that it falls into the wheel groove. The orderliness and punctuality of paper tubes. (4) The operator does not need to put his hands into the machine, so the safety performance is improved.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic structural view of the utility model.

Fig. 2 is a schematic diagram showing the shape of the feeding device, the shape of the wheel groove and the position of the cutting knife.

Specific embodiments As shown in Figure 1, two left and right brackets are arranged on the machine base 1, the left motor 10 is fixed on the upper end of the left bracket 5, and the right motor 14 is fixed on the upper end of the right bracket 18. In this example, the right support 18 is fixed on the support 1, and the left support 5 is slidably installed on the support 1. When the processing size needs to be adjusted, move the left support 5 on the support 1 and fix it with bolts.

The outer sides of the two left and right brackets are respectively installed with the top shaft 8 which is connected to the motor transmission and whose outer end is connected with the reciprocating drive device 6 through the connecting bearing 7 . Top shaft 8 is installed on the support by rolling bearing 9. Drive this top shaft 8 to rotate during motor work. A reciprocating drive device 6 in the form of an air cylinder is fixed on the support to drive the jack shaft to move horizontally. The reciprocating drive device 6 can also be other reciprocating drive forms such as cams, leading screws, chains, hem drives, etc.

The two brackets on the left and right are provided with jacking shaft holes 16 whose centers are on the same horizontal line, and the jacking shaft 8 and the jacking shaft holes 16 are arranged concentrically. The lower swing shaft 3 positioned below the centerline of the two top shaft holes 16 is arranged between the left and right brackets, and the lower swing drive device 17 installed on the support is connected to the lower swing shaft 3 by transmission. The lower swing drive device 17 can be an air cylinder The form can also be other reciprocating drive forms such as cams, leading screws, chains, and hem drives.
