Description
Technical Field
The utility model relates to a big circular knitting machine cropping spool.
Background
The existing circular knitting machine collects cloth through a paper tube sleeved on a scroll. The existing scroll is simple in structure and can only correspond to a type of paper tube.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model aims to provide a big circular knitting machine plaiting spool that can adapt to many specifications paper tube.
In order to achieve the above object, the utility model discloses a big circular knitting machine cropping scroll, include:
a hollow shaft tube;
more than two windows are uniformly arranged at the positions of the shaft tube close to the two ends along the circumferential direction of the hollow shaft tube;
a rotating shaft supporting plate is arranged in the shaft tube and close to the window;
a paper tube support tongue is hinged on the rotating shaft support plate corresponding to each window; the outer contour of the hinged side of the paper tube supporting tongue is circular; the outer contour of the hinged side of the paper tube supporting tongue is provided with meshing teeth;
a rotating shaft is coaxially arranged in the hollow shaft pipe, and meshing threads are arranged at two ends of the rotating shaft; the rotating directions of the two sections of engaged threads are opposite;
the meshing threads at the two ends of the rotating shaft are meshed with the paper tube support tongue meshing teeth.
Furthermore, a linear or cross-shaped groove is arranged at one end or two end parts of the rotating shaft.
Furthermore, a friction convex part is arranged on the outline of one end of the paper tube stay tongue far away from the hinge shaft.
The utility model discloses utilize the pivot both ends to be provided with the meshing tooth intermeshing that meshing screw thread and paper tube propped the tongue afterbody, can realize that the paper tube props the tongue and outwards props out through the window, can adapt to the paper tube of different models along with its difference that props out the angle.
Drawings

Fig. 2 is a first usage state diagram of fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings
As shown in fig. 1, the utility model discloses a big circular knitting machine cropping spool, include:
a hollow shaft tube 1;
more than two windows 2 are uniformly arranged at the positions of the shaft tube close to the two ends along the circumferential direction of the hollow shaft tube;
a rotating shaft supporting plate 3 is arranged in the shaft tube at a position close to the window;
a paper tube supporting tongue 4 is hinged on the rotating shaft supporting plate corresponding to each window; the outer contour of the hinged side of the paper tube supporting tongue is circular; the outer contour of the hinged side of the paper tube supporting tongue is provided with meshing teeth;
a rotating shaft 5 is coaxially arranged in the hollow shaft pipe, and meshing threads are arranged at two ends of the rotating shaft; the rotating directions of the two sections of engaged threads are opposite;
the meshing threads at the two ends of the rotating shaft are meshed with the meshing teeth of the paper tube supporting tongue. As shown in the figure, the rotating shaft is shorter than the hollow shaft tube, and both ends of the rotating shaft are positioned in the hollow shaft tube; therefore, the paper tube supporting tongue can be prevented from being driven to rotate by touching the rotating shaft; the shaft heads can be inserted into the two ends of the axle passenger according to requirements so as to be convenient to mount on the frame.
In order to facilitate the rotation of the driving rotating shaft, a linear or cross-shaped groove 6 is arranged at one end or two end parts of the rotating shaft. Therefore, the rotating shaft can be driven to rotate by a screwdriver or the like so as to rotate in or out the paper tube supporting tongue 4. A square or hexagonal adapter part can be arranged at the end of the rotating shaft according to requirements.
In order to fix the paper tube more stably, a friction convex part is arranged on the outline of one end of the paper tube stay tongue far away from the hinge shaft. The friction convex part can be a convex point, a friction tooth and the like, so that the friction force between the paper tube support tongue and the inner wall of the paper tube can be increased by utilizing the friction convex part.
The using process comprises the following steps:
initially, the paper tube supporting tongue 4 is positioned in the window 2 of the hollow shaft tube 1; after the paper tube is sleeved outside the hollow shaft tube 1, a tool is used for driving the rotating shaft to rotate; therefore, the meshing threads at the two ends of the rotating shaft drive the meshing teeth of the hinge of the paper tube supporting tongue to rotate, the far hinged shaft end of the paper tube supporting tongue is driven to rotate outwards from the surface until the outer contour of the paper tube supporting tongue is abutted against the paper tube, and the paper tube can be rotated and pushed and pulled to be positioned at a proper position; after the position is adjusted, the rotating shaft is rotated by means of the tool to clamp and fix the paper tube, and then the paper tube can be installed on the machine frame to carry out production operation. After the production operation is finished, the rotating shaft is rotated reversely by a tool, so that the paper tube support tongue is rotated inwards towards the window, and the paper tube (cloth roll) can be pulled out from the rotating shaft.
